Abstract

We theoretically demonstrate a switchable metamaterial with dual-mode resonance located at THz regime under normal incidence by reshaping metamaterial elements. The mode switching allows easily controlling the resonant absorption of the metamaterial from 0.49 THz to 0.53 THz, and from 1THz to 1.13THz, precisely. Such switchable dual mode metamaterial promises wide application in optical switches, tunable filter, and THz detectors.
