摘　　要：边界元法的基础上,描述了一种解决本征值问题的方法。首先给出适用于三维电磁问题的矢量边界积分方程,然后导出了本征值方程。为了计算本征值,在对谐振腔体的边界进行离散的过程中采用了常量单元。编制了计算机程序并给出了三个具体算例。结果表面,本方法所得到的数值结果与对应的解析解以及HFSS、Magic和CST等电磁仿真软件的数值计算结果符合得很好,证明了本方法的有效性。A method for the solution of eigenvalue problems with boundary element method is described.The vector boundary integral equation is first presented for three-dimensional electromagnetic problems.Then the eigenvalue equation is derived.To compute the eigenvalue,constant elements are adopted in the process of discretizing the boundary of the cavity.Computer programs are designed and three numerical examples are presented.The numerical results agree well with the analytical solutions and those from software such as HFSS,Magic and CST,which shows the validity of this method.
