本文先从一些具体的例予说明用经典场论的方法不可能从一个场的方程中得到电场的完全解,然后把这一结论推广到电磁场问题的普遍情况。从而得出,不论应用Tai的并矢格林函数法,还是Yaghjian的直接求解法都不可能求得关于电场的完全解的正确的表达式。
In this paper, we first explain from some concrete examples that it is impossible to obtain the complete solution of the electric field from the equation of a field by the method of the classical field theory, and then generalize this conclusion to the general situation of the electromagnetic field. It follows that it is impossible to obtain the correct expression for the complete solution of the electric field, no matter using the dyadic Green’s function method of Tai, or the direct solution of Yaghjian.
