June 8, 2022: Dielectric Coatings | The Science of Color

The vast majority of UHF North American broadcast antennas today are slotted cylinder pylon antennas, which offer benefits including smaller tower footprints, fewer parts, lower windload and superior pattern flexibility. Unfortunately for radio broadcasters, their narrow bandwidth characteristics were impractical for passing full-band FM signals. Just in time for the 2022 NAB Show and the company's 80th year in business, Dielectric has unveiled its innovation to resolve these bandwidth limitations with the FMP family of FM pylon antennas. Dielectric will demonstrate its benefits in Booth W7107 at the Las Vegas Convention Center, April 24-27. David Rusch discusses how these advances were realized with Dielectric President Keith Pelletier.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

In mid-September, Sinclair Broadcast Group-owned Dielectric first shared how the company literally changed how FM broadcast antenna manufacturers validate directional pattern studies for new FM broadcast antennas.This led Dielectric to submit a Petition for Rulemaking with the FCC. And, if the FCC moves forward with a NPRM and subsequently approves the rules, a process that could take just months, a move from physical to AI-driven simulated modeling could come to fruition.The engineering guys may get this, but those in the C-Suite may already have eyes glazed over. In this InFOCUS Podcast, presented by dot.FM, Keith Pelleiter explains this so the only thing glazed in their office is a Krispy Kreme donut.

Dielectric has changed how FM broadcast antenna manufactures validate directional pattern studies for new FM broadcast antennas. The company's groundbreaking research has resulted in the recent FCC filing of a Petition for Rulemaking, written with leading broadcast consultancy, Merrill Weiss Group, and expected to be approved this fall.The new rule paves the way for the first directional FM pattern verification rule change in 58 years — a rule change that passes the torch from physical to AI-driven simulated modeling. On this episode of Broadcast Dialogue - The Podcast, David Rusch talks with Keith Pelletier, General Manager of Dielectric, about the ramifications of this rule change for broadcasters in both the U.S. and Canada.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ether may be the life energy known as Chi or prana. It flows like water and is attracted to water. Ether is part of us and everything, and is throughout the universe. It has been measured in a few different ways by scientists in the area of astrophysics and in life sciences in humans and plants. It can be seen as blueish light in wet sand occasionally and may be the healing force in a wet sand or mud pack. Physics took a wrong turn in 1887 and is still on that wrong path of thinking that the long standing theory of ether filling space was proven wrong - null. No, zero effect was not measured, simply a smaller force of energy was measured than the 1887 experiment hypothesis had stated - so null results. Null means hypothesis was not proven, it does not mean 'zero'. See Physics took a wrong turn in 1887 and the meaning of null. - The first in a short series. Dielectric orgone blankets. Happy Birthday Einstein; Gravity. Ether theory applied - re-greening an African nation, Eritrea. Ether Theory? Our ticket to outer space?. Love and hate - we are a mixture and ether may respond in quantum ways responding to positive or negative thought - proof of that? No, Do we need more negativity though? No. Universal consciousness may involve quantum entanglement of free pairs of quarks - which can contain a holographic amount of information about a thing - or living being possibly. The Edinburgh Lectures on Mental Science, a book by Thomas Troward includes similar ideas about ether and the mental power of positive thinking. It was written in the 1920s before ether theory was completely dismissed due to Albert Einstein's work on relativity and gravity. Read online (gutenberg.org).

If you don’t know Ken Wheeler - he’s a translator of ancient Greek, Sanskrit and Pali texts, tatted from head to toe and author of “Uncovering the Missing Secrets of Magnetism”.  Wheeler is an iconoclastic figure within philosophical, metaphysical, scholarly and scientific circles who now appears to be spending most of his time making YouTube videos (on his Theoria Apophasis channel) about metaphysics, electromagnetism and camera equipment.  He also likes to crack the kinds of jokes one might expect from a 6th grader. Is he for real?  Noah and Cahlen discuss the man and some of the unexamined implications of his ideas.

Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store. Dielectric elastomers could offer an alternative to pneumatic actuators but they currently require complex and inefficient circuitry to deliver high voltage as well as rigid components to maintain their form— both of which defeat the purpose of a soft robot. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a dielectric elastomer with a broad range of motion that requires relatively low voltage and no rigid components.

A very small hologram that can be used across all different wavelengths of light and can be programmed with different images based on the direction of light that works because it's made from a material that doesn't absorb certain light and has other properties not found in nature.

The interaction of photons with individual quantum systems is a very fundamental process in physics. Thereby, the emission rate as well as the angular emission pattern of a quantum emitter are not only a function of intrinsic properties of the emitter itself, but are also strongly modified by its surrounding. For instance, by restricting the optical modes which are allowed at the position of the dipole, the emission rate can be strongly modified and the emitted photons can be directed into specific optical modes. This effect can be demonstrated by the interaction of a single optically active quantum emitter with the strongly confined optical mode of a single-mode dielectric waveguide. Efficient coupling of the emitter to the dielectric structure can be achieved by placing the quantum emitter inside the evanescent field of the guided mode. This evanescent field coupling mechanism is discussed and demonstrated experimentally. A single nitrogen-vacancy center (NV-center), hosted in a nanodiamond is deterministically coupled to a tapered optical fiber (TOF) via the evanescent field of its guided mode (coupling efficiencies exceeding 30% are predicted). By employing an AFM-based nanomanipulation technique, the diamond nanocrystal is placed on the nanofiber waist of the TOF. Beforehand, the diamond nanocrystal has been characterized to guarantee that it hosts only one fluorescing NV-center. While the diamond nanocrystal is optically exited, single photon fluorescence of the NV-center is detected at both outputs of the tapered optical fiber. This verifies the evanescent coupling of the emitter to the guided mode. In order to quantify the coupling, the comparison of the emission rate into free space with the rate into the fiber yields that 10.0(5) of the emitted photons are coupled into the tapered optical fiber. In the determination of this value, the orientation of the emitting dipoles and the emission pattern, which are modified by the TOF, have been considered. The NV-center features a broad emission spectrum which can be used to investigate the wavelength-dependence of the coupling. Comparing the spectra of the emission into the fiber mode with the emission into free space modes roughly resembles the expected wavelength dependency of the coupling efficiency. The evanescent coupling and the deterministic positioning of preselected fluorescing diamond nanocrystals, which has been demonstrated with the TOF, can be applied to other waveguide structures as well. Dielectric single-mode waveguides made of Ta2O5 on a SiO2 substrate promise similar coupling efficiencies to tapered optical fibers (above 30%). With the design of the on-chip wave-guiding structure being flexible, the combination with other optical on-chip elements is feasible, rendering it a promising platform for on-chip photonic experiments. Test structures of this waveguide design are realized using lithographic processes and are characterized. These waveguides are equipped with inverted taper structures to allow efficient off-chip coupling with butt-coupling to standard single-mode fibers. The evanescent coupling of a single quantum emitter to a singe optical mode can be used to efficiently collect emission of the quantum emitter. This can help building a compact single photon source and is beneficial for the optical read-out of the quantum emitter's internal degree of freedom, which can be either used as probe (sensing) or as information-storage. Utilizing the high coupling efficiency, for instance, the non-linearities of the quantum system can be exploited to build a single photon transistor. The evanescent coupling is very broadband (about hundred nanometers), allowing to efficiently collect emission from broadband emitters like the NV-center, but it can also be used for multi-wavelength manipulation schemes.

In dieser Arbeit berichten wir über die Beobachtung der dielektrischen Laserbeschleunigung nichtrelativistischer Elektronen mithilfe des inversen Smith-Purcell Effekts bei optischen Wellenlängen. Wenn die Phasengeschwindigkeit von evaneszenten Wellen nahe periodischer Gitterstrukturen mit der Elektronengeschwindigkeit übereinstimmt, kann eine vorwärtsgerichtete elektrische Feldkomponente das Elektron kontinuierlich beschleunigen. Dieser Effekt tritt jedoch nur im Nahfeld passender photonischer Strukturen auf, d.h., dass der Elektronenstrahl die Struktur in Abständen, die kleiner als die Wellenlänge sind, passieren muss. Für die Beschleunigung nichtrelativistischer 28keV Elektronen verwenden wir die dritte Raumharmonische eines Quarzgitters, die mittels Lichtpulsen eines Titan-Saphir-Oszillators angeregt wird. Wir messen einen maximalen Energiegewinn von 280eV, was einem Beschleunigungsgradienten von 25MeV/m entspricht. Dieser Wert ist vergleichbar mit dem Gradienten heutiger Radiofrequenz-Linearbeschleuniger. Um diese Beschleunigung zu erfahren, passieren die Elektronen die Gitteroberfläche in einem Abstand von weniger als 100nm. Im Rahmen dieser Arbeit beschreiben wir die Theorie der Elektronenbeschleunigung im Nahfeld von Gitterstrukturen und diskutieren Simulationsergebnisse zu dieser dielektrischen Laserbeschleunigung. Unsere Messergebnisse stimmen sehr gut mit den Simulationen überein und bestätigen deshalb die direkte Beschleunigung im Lichtfeld. Zusätzlich diskutieren wir die Elektronenbeschleunigung in Doppelgitterstrukturen, das Dephasieren nichtrelativistischer Elektronen, sowie den Raumladungseffekt, der den Spitzenstrahlstrom in diesen neuartigen, auf Mikrostrukturen basierenden Beschleunigern begrenzt. Die hier verwendeten photonischen Gitterstrukturen können direkt aneinandergereiht werden und erfüllen damit die Voraussetzung für skalierbare Linearbeschleuniger. Außerdem sind unsere Strukturen kompatibel mit den Mikrostrukturen, an denen die dielektrische Laserbeschleunigung relativistischer Elektronen zeitgleich durch unsere Kollegen in Stanford demonstriert wurde. Das Potenzial dielektrischer Laserbeschleuniger liegt in dem bis zu zwei Größenordnungen höheren Beschleunigungsgradienten verglichen mit konventionellen Beschleunigereinrichtungen, was sich letztendlich auf die größere Zerstörschwelle dielektrischer Materialien bei optischen Wellenlängen im Vergleich zu Metallen im Radio- und Mikrowellenbereich zurückführen lässt, die eine erhöhte Oberflächenspannungsfestigkeit zur Folge hat. Dieser erhöhte Beschleunigungsgradient könnte den Bau von deutlich kompakteren und kostengünstigeren Beschleunigern erlauben. Wir geben einen Ausblick auf den möglichen Aufbau solcher zukünftiger optischen Beschleuniger und auf deren potentiellen Anwendungen in kompakten Freie-Elektronen-Lasern.

Antennas are at the heart of modern radio and microwave frequency communications technologies. Because of their efficient coupling to light propagating in free space, antennas form the basis for transmitting and receiving electromagnetic radiation. Using metallic nanostructures, researchers have extended antenna concepts to the optical frequency domain and realized many advancements in nanophotonics [1]. However, recent research has begun to exploit the scattering resonances of high-permittivity particles to realize all-dielectric optical antennas. In this talk, we experimentally and theoretically characterize the resonant modes of subwavelength rod-shaped dielectric particles using Mie theory and infrared spectroscopy. We derive and verify a variety of general analytical results [2] applicable to all dielectric antenna systems and demonstrate novel antenna-based light emitters (transmitters) and photodetectors (receivers) [3,4]. External to the particle surface, the electromagnetic fields are indistinguishable from that of a point source and these structures can be thought of as artificial electromagnetic “atoms." Unlike real atoms, which resonate like electric dipoles only, dielectric antennas can be engineered to resonate in higher order modes. We discuss the distinct electromagnetic field profile for the observed antenna resonances and demonstrate that antennas can be arranged into a particle array to form an artificial electromagnetic material with a negative index of refraction [5]. Finally, we discuss how the concepts presented here may be extended to impact a variety of visible and infrared frequency photonic technologies.
