A gradient index lens for microwave radiation. The lens includes a plurality of electric field coupled resonators wherein each resonator has a resonant frequency. The resonators are arranged in a planar array having spaced apart side edges and spaced apart top and bottom edges. The resonant frequency of the resonators varies between at least two of the spaced edges of the array in accordance with the desired properties of the lens.
