Abstract: The recently developed class of artificially structured composite materials, termed metamaterials, has shown increasing importance in accomplishing necessary functional devices for THz applications. We have created a series of novel planar electric metamaterials operating at THz frequencies. Alteration of substrate properties has resulted in actively and dynamically switchable THz metamaterial devices. High efficiency, all-electronic THz switching and modulation operating at room temperature have been accomplished by the use of a hybrid of metamaterial and Schottky diode structure. Dynamic switching of THz radiation was also achieved by photoexcitation of the semiconductor substrate, where ultrafast switching has been demonstrated by the use of an ErAs/GaAs nanoisland superlattice substrate.
