Transmission properties of terahertz pulses through semiconductor split-ring resonators

摘要

In this paper, two novel planar terahertz semiconductor split-ring resonators are successfully constructed and measured using the commercial software CST Microwave Studio. They exhibit a duelband and a triple-band transmission property within the frequencies ranging from 0.1 THz to 3THz. We have simulated the dual-band planar metamaterial with two distinct electric resonances at 0.81 THz and 1.818THz, and triple-band planar metamaterial with three distinct electric resonances at 0.543THz, 1.044THz, and 1.506THz. These developments are further steps towards the development of broadband terahertz devices.
