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.

In this study, a new terahertz cross-shaped metamaterial bandpass filter is designed, simulated and fabricated. It provides a very good transmission coefficient and much lower unwanted frequencies than other filters do. The simulation is conducted by the CST STUDIO software and the FDTD method.
