Abstract:

A device includes a waveguide layer formed on a substrate. An ultra-small resonant structure emits electromagnetic radiation (EMR) in the waveguide layer. One or more circuits are formed on the waveguide layer and each operatively connected thereto to receive the EMR emitted by the ultra-small resonant structure. The waveguide layer may be transparent at wavelengths corresponding to wavelengths of the EMR emitted by the ultra-small resonant structure. The EMR may be visible light and may encode a data signal such as a clock signal.

US Classification:

250397, 2504921

Abstract:

A focal plane array electromagnetic radiation detector includes an array of micro-electromagnetic resonant detector cells. Each micro-electromagnetic resonant detector cell may include an ultra-small resonant structure for receiving an electromagnetic wave and adapted to angularly modulate a charged particle beam in response to receiving an electromagnetic wave. Each micro-electromagnetic detector cell may include a detector portion that measures the angular modulation of the charged particle beam.

Abstract:

An antenna system includes a dielectric structure formed on a substrate; an antenna, partially within the dielectric structure, and supported by the dielectric structure; a reflective surface formed on the substrate. A shield blocks radiation from a portion of the antenna and from at least some of the dielectric structure. The shield is supported by the dielectric structure.

International Classification:

US Classification:

2504941, 25049223, 250396 R, 977950, 455323, 455329

Abstract:

A display of wavelength elements can be produced from resonant structures that emit light (and other electromagnetic radiation having a dominant frequency higher than that of microwave) when exposed to a beam of charged particles, such as electrons from an electron beam. An exemplary display with three wavelengths per pixel utilizes three resonant structures per pixel. The spacings and lengths of the fingers of the resonant structures control the light emitted from the wavelength elements. Alternatively, multiple resonant structures per wavelength can be used as well.

Abstract:

A device couples energy from an electromagnetic wave to charged particles in a beam. The device includes a micro-resonant structure and a cathode for providing electrons along a path. The micro-resonant structure, on receiving the electromagnetic wave, generates a varying field in a space including a portion of the path. Electrons are deflected or angularly modulated to a second path.

International Classification:

H01J 3/30

US Classification:

250399, 250396 R, 250397, 329302, 398202, 455313

Abstract:

Nanoantennas are formed on a substrate (e. g. , silicon) and generate light via interactions with a charged particle beam, where the frequency of the generated light is based in large part on the periodicity of the “fingers” that make up the nanoantennas. Each finger has typical dimensions of less than 100 nm on the shorter side and typically less than 500 nm on the longer, but the size of the optimal longer side is determined by the electron velocity. The charged particle may be an electron beam or any other source of charged particles. By utilizing fine-line lithography on the surface of the substrate, the nanoantennas can be formed without the need for complicated silicon devices.

International Classification:

G09G 1/00

US Classification:

250396R, 250397, 315 543

Abstract:

When using micro-resonant structures, it is possible to use the same source of charged particles to cause multiple resonant structures to emit electromagnetic radiation. This reduces the number of sources that are required for multi-element configurations, such as displays with plural rows (or columns) of pixels. In one such embodiment, at least one deflector is placed in between first and second resonant structures. After the beam passes by at least a portion of the first resonant structure, it is directed to a path such that it can be directed towards the second resonant structure. The amount of deflection needed to direct the beam toward the second resonant structure is based on the amount of deflection, if any, that the beam underwent as it passed by the first resonant structure. This process can be repeated in series as necessary to produce a set of resonant structures in series.
