Abstract

A metamaterial that is embedded in an in-plane-switching dual-frequency liquid crystal cell is used to develop an electrically controllable terahertz (THz) metamaterial. The resonance peak of the metamaterial can be redshifted and blueshifted as the frequency of an external voltage is switched, and the response times for the redshift and blueshift are 1.044 and 1.376 ms, respectively. A simulation confirms the spectral redshift and blueshift. The variation in peak frequency as a function of applied frequency at the external voltage is presented. Experimental results show that the resonance peak of the metamaterial can be continuously tuned within a frequency range of 15 GHz as the applied frequency is switched between 19 and 22 kHz. Therefore, this metamaterial is a continuously tunable and fast-response THz filter and could be used for THz imaging and THz telecommunications.
