Abstract

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).
