Abstract :
A metamaterial with electronically tunable negative-refractive index region is presented. The proposed structure is loaded with interdigital capacitors fabricated on a barium strontium titanate thin film. When a static electric field is applied to the series connected elements in the metamaterial, the region with negative refractive index is tuned over the WR-137 band. Computer simulation of the unit cell is presented. Experimental measurement of the completed structure in a parallel plate wave guide will be presented at APMC 2009.
