Abstract
This paper describes a terahertz filter based on frequency selective surface with periodic Jerusalem cross slot cell. The filter is a two-stage band-pass filter fabricated with double-side Au film and the central frequency is 220GHz. The electromagnetic modeling, simulation and analysis of the bandpass filter are presented. The influence of the dimension of the Jerusalem cross cell on the transmission characteristics of the band-pass filter is discussed. By optimizing the dimension of the Jerusalem cross cell, the band-pass filter shows that the insertion loss is −1.9dB∼ −1.6dB with a 3dB bandwidth of 8GHz, and the return loss is less than −8.9dB.
