Abstract:
1. A metamaterial microwave lens comprising: an array of electronic inductive capacitive cells, each cell having an electrically conductive pattern which responds to incident microwave electromagnetic energy as an LC resonator, said electrically conductive pattern disposed on a substrate, at least one of said cells including at least one MEMS device having two sides and movable in response to an electrical bias between at least two positions to thereby vary the resonant frequency of said at least one cell, an electrical insulating layer extending along and over only a portion of said pattern of said at least one cell, said insulating layer extending to said MEMS device, an electrically conductive strip extending over said insulating layer such that said conductive strip is electrically insulated from said pattern, the sides of said conductive strip being spaced inwardly from sides of said pattern so that said conductive strips overlie only a portion of said pattern, said conductive strip being electrically connected to said sides of said MEMS device and said insulating layer being sandwiched between said conductive strip and said conductive pattern.
