Abstract
A metamaterial microwave lens having an array of electronic inductive capacitive cells in which each cell has an electrically conductive pattern which corresponds to incident electromagnetic radiation as a resonator. At least one cell has a first and second electrical sections insulated from each other and each which section has at least two legs. A static capacitor is electrically connected between one leg of the first section of the cell and one leg of the second section of the cell. A MEMS device is electrically disposed between the other legs of the first and second sections of the cell. The MEMS device is movable between at least two positions in response to an electrical bias between the first and second sections of the cell to vary the index of refraction and resonant frequency of the cell.
