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.
