| 摘 要： | 简单介绍了用于分析任意口径问题的通用频域方法——广义网络原理,并利用边界积分法和广义网络原理分析导电平板上任意缝隙填充各向异性介质时TM波的散射及传输特性.由于缝隙填充各向异性介质的情形尚未见公开文献报道,作为验证,将本方法退化计算各向同性介质填充时缝隙的散射和传输特性,并与文献结果进行比较.最后,给出了缝隙填充各向异性介质时的算例.

| Abstract: | The electromagnetic characteristics of transmission and scattering properties of a slit in a conducting plate filled with anisotropic media for TM polarization are dealed with. A general frequency domain method-the Generalized Network Formulation is simply introduced. To the best of our knowledge, this problem has not been dealt with in publications. The boundary element method(BEM) and Generalized Network Formulation are implemented to solve this problem and some examples are presented. The computed results are in agreement with the one obtained in isotropic case.This illustrates the feasibility of presented scheme. Two examples of the RCS and transmission coefficients for a slit filled with anisotropic media are also presented. |
