Electrically tunable metamaterial for polarization-independent terahertz modulation

Electrically tunable metamaterial for polarization-independent terahertz modulation

We present a polarization-insensitive, electrically tunable metamaterial operating at terahertz (THz) frequencies and demonstrate the fast modulation of a propagating THz wave. The structure is composed of gold crosses on n-doped gallium arsenide (GaAs).
