摘要： A high impedance (Hi-Z) wire effectively transparent to electromagnetic radiation polarized in the direction of the wire, within an operating frequency band. The Hi-Z wire is sheathed with a thin layer of resonant structures that are small compared to the wavelength, and behave as a kind of photonic band gap (PBG) material. A frequency-selective polarizer comprising a plurality of Hi-Z wires disposed parallel to one other in a grid. A wire grid reflector that enables stepwise phase control of the reflected wave and focusing of radiative power, the reflector comprising Hi-Z wires interspersed with conventional wires disposed parallel to one another in a grid.

摘要： A tuneable impedance surface for steering and/or focusing a radio frequency beam. The tunable surface comprises a ground plane; a plurality of elements disposed a distance from the ground plane, the distance being less than a wavelength of the radio frequency beam; and a capacitor arrangement for controllably varying the capacitance of at least selected ones of adjacent elements. A method of tuning the high impedance surface allows the surface to mimic, for example, a parabolic reflector or a diffraction grating.

摘要： A method for improving the efficiency of antennas having transparent thin-film conductive surfaces, and antennas improved by the method are disclosed. For a selected frequency of antenna operation, values for surface current density in areas distributed over the surface of the thin-film are determined. Regions of the surface containing areas having concentrated current flow are identified based upon the determined values of current density. Antenna efficiency is improved by increasing conductivity in areas of the thin-film surface found to have concentrated current flow. The method enables the improvement of the efficiency of antennas having transparent thin-film conducting surfaces, without unnecessarily obstructing the optical view through the thin-film surfaces of the antennas.

摘要： A method and apparatus for creating uniform heating of an microwave absorptive target. A microwave housing has a longitudinal axis and propagates a waveguide mode at an operating frequency. The target is located in an axial cross-sectional area relative to the longitudinal axis. First layer conductive strips are layered proximal to an inner wall of the microwave housing, substantially parallel to the longitudinal axis and being separated from an adjacent first layer conductive strip by a respective first layer gap, the inner wall acting as a ground plane. Second layer conductive strips are layered proximal to the first layer of conductive strips, parallel to the longitudinal axis and being separated from an adjacent second layer conductive strip by a respective second layer gap. Each first layer gap is centered under a respective second layer conductive strip and each second layer gap is centered over a conductive layer.
