摘要

It is about fifty years since dyadic Green' s functions (DGF) were used to solve electromagnetic boundary problems. However, by 1971 the DGF under normal boundary conditions had been studied systematically with the method of Ohm-Rayleigh by C. T. Tai,Afterwards, C. T. Tai presented the method of G_m for solving irrotational vector fields. For some complicated systems such as dielectric loaded systems, layered dielectric systems and combined systems, it is difficult to determine M and N, and it is very difficult and complicated to derive their DGF. To solve those problems, Song Wenmiao presented a method by which DGF were solved by means of scalar Green's functions. However, the method in ref. [3] is only suited to solving the DGF of solenoidal vector fields, but not suited to deriving the DGF of irrotational fields. Improving the method in ref. [3], we develop a structural method in this note for solving DGF. It is suited to solving both the DGF of irrotational fields and the DGF of solenoidal fields.

Tai提出了解决旋转矢量场的G_m方法。对于某些复杂的系统，例如介电负载系统，分层介电系统和组合系统，很难确定M和N，并且推导它们的DGF也非常困难和复杂。为了解决这些问题，宋文m提出了一种利用标量格林函数解决DGF的方法。但是，参考文献中的方法。文献[3]仅适用于求解螺线管矢量场的DGF，但不适用于推导非旋转场的DGF。改进参考文献中的方法。 [3]，我们在本说明中开发了一种解决DGF的结构方法。它适用于求解非旋转场的DGF和螺线管场的DGF。
