摘要

本文介绍了一种基于频率选择面和周期性耶路撒冷交叉槽单元的太赫兹滤波器。该滤波器是采用双面金膜制作的两级带通滤波器，中心频率为220GHz。对该带通滤波器进行了电磁建模、仿真和分析。讨论了耶路撒冷交叉单元尺寸对带通滤波器传输特性的影响。通过优化耶路撒冷交叉单元的尺寸，该带通滤波器显示，在3dB带宽为8GHz的情况下，插入损耗为−1.9dB ~−1.6dB，回波损耗小于−8.9dB。

A terahertz frequency selective surface band-pass filter

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.
