摘要

提出了一种利用开放式横向电磁箱测量散射参数的简易系统。利用时域有限差分(FDTD)原理对散射参数进行了模拟。同时，对经典的槽选频面(FSS)进行了单元格模拟，结果与全波模拟结果吻合较好。仿真结果表明，该系统在1 ~ 8 GHz频率范围内具有良好的场均匀性和较低的反射率，可用于吸波器的吸光度测量、FSS的透射和反射系数测量、FSR (frequency Selective Rasorber)的透射和反射系数测量。

A Wideband Open TEM cell to Measure the Frequency Response of a Frequency Selective Surface

A simple system for the measurement of scattering parameters is presented utilizing an open Transverse Electro-Magnetic (TEM) cell. The scattering parameters are simulated in the principle of Finite Differences Time Domain (FDTD). Meanwhile, a classical slot Frequency Selective Surface (FSS) was simulated in the proposed TEM cell, and the results are in greet agreement with the full-wave simulated results in unit cell way. The simulation result shows a good field uniformity and low reflection in the frequency range of 1 to 8 GHz, which may be applied in absorptivity measurement of absorber, transmission and reflection coefficient of FSS, Frequency Selective Rasorber (FSR).
