摘    要:文章将有限元—边界积分法(FE-BI)与渐进波形估计技术(AWE)相结合应用到宽带电磁散射特性分析中.首先应用该理论计算导体方柱的宽带雷达散射界面(RCS)并与FE-BI逐点计算进行了比较,接着计算了导体表面覆盖不同密度、不同碰撞频率的等离子体的宽带RCS.计算结果表明,FE-BI结合AWE技术比有限元逐点计算省时,且...

关 键 词:有限元—边界积分法  渐进波形估计  等离子体  宽带雷达散射截面

Abstract:Based on the finite element-boundary integral(FE-BI) method and the asymptotic waveform evaluation(AWE) technique,an efficient method for analyzing the wide-band electromagnetic scattering is proposed.Firstly,the wide-band radar cross section(RCS) of a perfectly conducting square is computed by using the proposed method,and the result is compared with that obtained by the FE-BI point-by-point method.Then the wind band RCS of the square coated with plasma of different density and collision frequency is compu...
Keywords:finite element-boundary integral(FE-BI) method  asymptotic waveform evaluation(AWE)  plasma  wide-band radar cross section(RCS)
