The numerical analysis model for ISD and UAE was established and also was used to simulate the cross loop slot cell FSS transmission performance by the finite element and periodic moment method program. The double layer cross loop aperture FSS configuration designed was used as the numerical model. As a result of the numerical analysis  it is shown that both ISD and UAE produce insertion transmission loss (ITL) and insertion phase distortion (IPD) directly. Furthermore  ISD results in much loss of the amplitude of the transmitted signal for the FSS than UAE. It is significant for the designer for the multiplayer FSS to assign the fabricated error of the FSS dielectric layers. The UAE introduces the insertion phase variation badly.   A statistical analysis of the amplitude and phase of earth polar shift in time-frequency domain 期刊论文  OAI收割 CHINESE ASTRONOMY AND ASTROPHYSICS, 2001, 卷号: 25, 期号: 3, 页码: 364-370 作者:  Ke, XZ;  Li, XH;  Deng, FL   |  收藏  |  浏览/下载：10/0  |  提交时间：2021/11/29 wavelet analysis  polar shift  statistic analysis  periodic variation
