Abstract:
1. A metamaterials 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 a resonator, at least one cell having a first and a second electrical sections electrically insulated from each other, each section having a central leg and two spaced apart and parallel linear side legs, a static capacitor electrically connected in series with said central leg of said at least one cell first section and one leg of said at least cell second section, a pair of MEMS devices, one MEMS device electrically in series with each of said side legs of said first and second sections of said at least one cell, each MEMS device having a cantilever portion of said first section which overlies a portion of said second section of said at least one cell and movable between at least two positions in response to an electrical bias between said first and second sections of said at least one cell to thereby vary the capacitance of each said MEMS device and thereby vary the resonant frequency of said at least one cell, and a first conductive strip which electrically connects said first sections of said cells together, and a second conductive strip which electrically connects said second sections of said cells together.
