We report metamaterial terahertz (THz) bandpass filters with tunable dual-band selectivity.
The shift in the center frequency of the device is achieved by actively modifying the effective …

In this paper, a second-order frequency selective surface (FSS) made of miniaturized
elements is proposed and designed for terahertz applications. The FSS is composed of two …

This paper presents a novel graphene-on-insulator (GOI) band-stop filter in the mid-infrared
region. The finite-difference time-domain method is used to model our GOI basic and …

Integrating tunable characteristics and multiple functions into a single metasurface attracts
more and more attention. Herein, a reconfigurable bifunctional metasurface is proposed to …
