High-Efficiency Flexible Terahertz Metamaterial

Abstract

A high-efficiency flexible terahertz (THz) metamaterial is presented, which is composed of parabolic- shape configuration. The device exhibits the larger tunabilities of single-band and dual-band resonances with ultra-narrow bandwidth. It possesses the multifunctionalities of single-band and dual-band switch and polarization switch for the realization of programmable metamaterials.
