摘要
针对非均匀正交各向异性媒质中的电磁场问题，给出了相应的约束方程和定解条件；对边值问题及其变分问题的等价性进行了证明．在此基础上建立了相应的有限元方程。
This paper aims at the problem of electromagnetic field in inhomogeneous orthotropic medium. The equations and conditions which associate with this problem are given. The equivalence of the problem to define solutions and its problem of variation is proved. On this foundation, the equations of finite element are built and used for calculating by computer program.
