摘要

摘要: 为了阐明电磁场和变形介质之间能量传递的详细机理,这篇论文选取整体的场方程作为出发点,给出变形介质电动力学的广义Poynting定理.然后按照对电磁体积力的一些特殊的假设,推导出这个定理的几种特殊的形式.

Abstract: This paper establishes the generalized pointing theorem for the electro dynamics of deformable media with a view to shedding some light on the detailed mechanism of energy transfer between the electromagnetic field and the deformable media.Global field equations are chosen as the starting point and specialized forms of theorem are derived based on the special vostulates for the electromagnetic body force.
