摘要

用Galerkin矩量法计算电场积分方程的方法

数值计算、分析了装配误差引起双屏FSS频率响应衰减变化特性。由实际经验建立了双屏FSS(频率选择表面)装配误差物理和结构模型

并提出了具体数值分析计算方法。基于数值分析结果表明

装配误差为单元周期长度10%时

频率响应幅值衰减最大; 当装配偏移方向与入射波极化方向一致时

产生相位插入延时并且相位与频率关系曲线发生变形;当装配偏移方向与入射波极化方向正交时

出现较大相位延迟。

Abstract

With the Galerkin moment method used in electric field integral equation

the frequency response attenuation performance produced by the fabrication error of two-layer Frequency Selective Surface(FSS) in the double screen frequency selective filter was analyzed. Based on the practical experience

the fabrication error analysis and construction models were built up. Moreover the practical numerical algorithm was proposed. According to the results of the numerical analysis

it is found that the amplitude attenuation of the double FSS frequency response is up to maximum value when the fabrication error is equal to a tenth unit cell periodic size. Further there is the phase delay and distortion when the fabrication excursion is parallel to the incident wave polarized direction. And there is much more phase delay

when the fabrication excursion is perpendicular to the incident wave polarized direction.
