金属介质混合目标电磁特性的快速分析

Fast analysis of a mixture of conducting and dielectric objects

将自适应积分算法与基于体面混合积分方程的矩量法相结合快速分析任意结构金属/介质混合目标的电磁散射和辐射特性。通过将传统矩量法的阻抗矩阵分为两部分且采用不同的方法进行处理计算,提高了矩量法的计算速度并大幅度缩减了需要的计算机内存占用量。最后,分别用传统的矩量法与结合自适应积分快速算法的矩量法计算了三个典型例子,通过比较充分说明了文中方法的有效性。

An accurate and efficient method that combines the adaptive integral method （AIM） and the method of moments （MoM） based on the coupled volumesurface integral equation （VSIE） is presented to calculate the electromagnetic scattering and radiation properties of arbitrarily shaped metallic and dielectric targets. The AIM eliminates the need to generate and store the usual impedance matrix of MoM by dividing it into two parts and dealing differently. Three numerical examples are presented for arbitrarily shaped metallic and dielectric targets to demonstrate the efficiency of this technique.
