The Design of Split Ring Resonator (Srr) Based Terahertz Bandpass Filter and Comparison of Various Types of Filters.

Abstract

Terahertz (THz) research has practiced an amazing progression in the past two decades. Terahertz filters plays a key role in THz applications. Terahertz filters with high bandwidth, tunable center frequency, and low insertion loss are the challenging design. This article comprises the investigation of the frequency response of terahertz filters using various metamaterials, frequency selective surfaces, and parallel plate waveguides. The proposed work includes the design of SRR based terahertz bandpass filter with tunable center frequency and bandwidth. Also, the proposed THz filters is simulated using the Comsol software and the simulated results are observed. This proposed design is used for numerous applications like spectroscopy, wireless communication, and imaging, etc.
