A MEMS metamaterial for dynamic terahertz wave switching

A terahertz (THz) dynamic switch with polarization dependence is proposed with MEMS metamaterial method. The split ring resonators (SRRs) are located on a silicon-on-insulator (SOI) wafer, where the buried oxide (BOX) is etched to let the silicon layer together with the SRRs work as an electromechanical shutter to control the incident THz wave propagation. Electrostatic actuation is employed for the shutter operation.
