二维涂敷导体柱电磁散射特性的有限元分析

本文利用有限元一边界积分方程混合方法计算一个介质涂敷二维导体柱的电磁散射特性。文中利用有限元算法来计算柱体虚构边界内部场，用边界积分方程法计算虚构边界外部场，虚构边界上通过场的连续性耦合，得到一个内部场和边界场解的耦合方程组，从而计算出边界外部任何位置的散射场及雷达散射截面。所得结果与其它文献中的精确结果比较，吻合很好。

Analysis of Electromagnetic Scattering from a 2-D Coated Cylinderby the Finite Element Method

In this paper,Finite Element-Boundary Integral Method is proposed to analyze the electromagnetic scattering of a 2-D RAM-Coated cylinder. It uses finite method to compute the scatter field in the fictitious boundary and utilizes boundary integral method to get the scatter field out of the boundary. It puts to use the continuity of the scatter field on the boudary to get the formation of 2 -D Finite Element -Boundary Integral formulation,and the result is compared with the results published in literature,goo...
