Abstract: An electromagnetic energy concentrator uses a prism and waveguide with a gap layer of uniform thickness disposed between the prism and a first surface of waveguide. Energy detectors, which may be photovoltaics or miniaturized antenna elements are disposed adjacent to and co-extensive with a second surface of the waveguide. The detectors operate in each of at least two bands; a distance between detectors operating in a given band depends on a wavelength in the given band.

Abstract: A cylindrically symmetric satellite antenna that provides directional and omnidirectional operating modes in a compact form factor. Feed points located at the top of the cylindrical structure provide increased platform isolation. Combining networks, disposed below or within the cylindrical structure, may be replaced with inexpensive baluns composed of coaxial line sections.

Abstract: An compact manpack format antenna operating over a broad bandwidth. In one arrangement, the antenna is formed from a set of five hollow cylindrical conductive elements. Several cylinders provide, for example, a VHF/UHF radiator section and other cylinders form an L-band radiator section. A bottom leg of the L-band section operates as part of the VHF/UHF section via coupling between that lower L-band leg and the VHF/UHF section. This coupling arrangement reduces the required overall physical length of the antenna.

Abstract: Detection of objects such as a buried explosive device while operating from a moving platform using a radio frequency emission system having two modes. An electromagnetic wave emission and detection system operates in a first mode to locate objects of interest and in a second mode to determine if an object contains explosive materials. In the first mode, the emission and detection system preferably operates as a subwavelength focusing, wideband, superlens using a near field super gain synthetic aperture continuous wave (CW) swept radar. In the second mode the system preferably enabled after detection of an object in the first mode, uses chemical detection methods such as Nuclear Quadrupole Resonance (NQR).
Abstract: A programmable transversal structure that may serve as a filter, or more generally, a transversal network. A pair of time delay elements are implemented using one or more grating control propagation path structures, multilayer waveguides with configurable gaps, or variable impedance meander lines. Electro active actuators responsive to bandwidth, center frequency, and stop band attenuation control inputs control the delay of such elements. Impedance elements are distributed between the time delay elements to provide the desired transversal response.

Abstract: Nuclear quadrupole resonance measurement using two or more wire loop(s) within a space to define a portal, and driving the wire loop(s) with a baseband digital transmitter generating a chirped or stepped signal, to create a corresponding varying electromagnetic field within the portal. Coherent emissions reflected thereby are detected through a directional coupler feeding the transceiver. The detected coherent emissions are processed with a matched filter to determine presence of a target object within the portal.

Abstract: A photonic antenna uses a traveling wave fed, surface wave excited, dielectric waveguide. One or more antenna elements are arranged in a line or other array. An optical interconnect is provide by depositing the waveguide structure on the system of antenna elements, and the photodiode detectors on the waveguide, or wafer bonded to the waveguide core. Optical sources are butt coupled to the edge of the waveguide via wafer bonding or as part of a deposition process. The device acts as a free-space optical transceiver embodied in an integrated photonic antenna and waveguide structure, and provides high speed, spectrally broadband response; it also inherently includes an open architecture for implementing Wavelength Division Multiplexing (WDM).

Abstract: A neuromorphic parallel image processing approach that has five (5) functional layers. The first performs a frequency domain transform on the image data generating multiple scales and feature based representations which are independent of orientation. The second layer is populated with feature based representations. The third layer, an object class recognizer layer, are fused using a neuromorphic parallel processor. Fusion of multimodal data can achieve high confidence, biometric recognition.
