METHODS AND APPARATUS FOR CONTROLLING A SURFACE SCATTERING ANTENNA ARRAY

摘要

An array of scattering and/or reflector antennas are configured to produce a series of beam patterns, where in some embodiments the scattering antenna and/or the reflector antenna includes complementary metamaterial elements. In some embodiments circuitry may be configured to set a series of conditions corresponding to the array to produce the series of beam patterns, and to produce an image of an object that is illuminated by the series of beam patterns.
