摘要

本文介绍了一种采用电磁晶体(EMXT)表面作为顶壁和底壁的矩形波导带阻滤波器。EMXT表面有一个带隙，可以阻止电磁波沿着波导传播。采用近似集总元电路模型分析了波导滤波器的色散特性。基于所提出的波导滤波器设计并表征了一个w波段原型。实验结果表明，该系统的抑制带以97 GHz为中心，抑制电平为16 dB。

A W-Band Waveguide Band-Stop Filter Using Electromagnetic Crystal (EMXT) Surface

A rectangular waveguide band-stop filter using electromagnetic crystals (EMXT) surface as the top and bottom walls is presented in this letter. The EMXT surface has a band gap that can prevent electromagnetic wave from propagating along the waveguide. Dispersion properties of the waveguide filter are analyzed using an approximated lumped-element circuit model. A W-band prototype based on the proposed waveguide filter is designed and characterized. The experimental results show a rejection band centered at 97 GHz and a rejection level of 16 dB.
