Abstract

In this paper, we propose a numerical formula to calculate time-harmonic electromagnetic field interacting with three-dimensional elastic body. The formula is based on the method of fundamental solutions. Firstly, we perform Helmholtz decomposition on the displacement field. The problem will transform into a coupled bounded problem including a scaler Helmholtz equation, a vector Helmholtz equation and a Maxwell equation. Then, we use the method of fundamental solutions to solve the new problem. Finally, we provide some examples to demonstrate the effectiveness of the proposed method. We construct the exact solutions for the boundary value problem to verify the accuracy and present a comparative study with the Galerkin scheme.

基于基本解方法的三维弹性体时谐电磁场无网格求解方法

本文提出了一个计算时谐电磁场与三维弹性体相互作用的数值公式。这个公式是基于基本解的方法。首先，对位移场进行亥姆霍兹分解。该问题将转化为包含标量亥姆霍兹方程、矢量亥姆霍兹方程和麦克斯韦方程的耦合有界问题。然后，我们用基本解的方法来解决新问题。最后，通过算例验证了所提方法的有效性。我们构造了边值问题的精确解来验证其准确性，并与Galerkin格式进行了比较研究。
