Latest Patents

One of his latest inventions is the Millimeter Wave Power Generator. This innovative device combines two laser beams, tuning the beat frequency to achieve the desired millimeter wave value with an opposing pair of millimeter wave cavities. The combined beam is diffracted onto a plurality of externally powered, modulation doped field effect photodetectors (MDFEPs). Additionally, a plurality of antennas is provided, one between each pair of adjoining MDFEPs. The antennas are parallel, and each is driven by the MDFEPs at its ends. The back propagating millimeter wave radiation is reflected forward by a wire grid parallel to the antennas. This grid is situated between the diffractor and the MDFEPs, and is spatially tuned to constructively interfere the reflected back propagating with the forward propagating millimeter wave radiation.

Another significant patent is the Pyroelectric Thermal Detector Array. This thermal detector array includes a substrate layer with a pyroelectric layer attached to the substrate. A plurality of detector regions is defined in the pyroelectric layer by openings through the layer. An array of cavities in the substrate surface separates the detector regions from the surface. First and second electrodes are placed on opposite sides of each detector region or on a single side in a coplanar embodiment. The array is joined to a signal processing device by means of corresponding metallic contacts on the pyroelectric layer and the processing device.
