Paper Abstract

We propose a high-transmission dualband terahertz bandpass filter by exciting multiple resonances of a composite metamaterial. The filter is composed a single layer of metal-dielectric-metal artificial structure and possesses two pronounced passbands centered at 0.97 THz and 1.37 THz, respectively. Both the passbands show high transmissions up to 90 % and also excellent band-edge transitions in the special terahertz-gap regime based on the simulations. In addition, we promise an effective approach to manipulate such electromagnetic properties of the metamaterial through realizing all the mechanisms for each resonant mode of the metamaterial. A potential terahertz device, broadband terahertz bandpass filter with almost 0.5-THz bandwidth, after structural modulation from the same composite metamaterial is also delivered in this work.
