Design and simulation of a new narrow terahertz bandpass filter

Abstract

In this paper, a new THz bandpass filter, referred to as ‘a spider filter,’ is designed, simulated and analyzed. According to the study of different samples of bandpass filters in the range of 0.1–3 terahertz, the proposed filter has proved to have a very good transmission coefficient and much lower unwanted frequencies than the other bandpass filters ever made.
