摘要

电磁问题中有很大一类是研究天线和散射理论

即由封闭电路系统向空间开放系统的能量转换.本文给出了激励源和加载网络统一的普遍电路模型;并具体给出了广义矩阵型Ohm's定律

使路和场的相互作用统一于其中.文中指出源和加载网络作为路对场有耦合作用

从而会影响近场与辐射方向图.

Abstract

An analysis of the antenna and scattering theory is an important part in the electromagnetic problems

which describes the energy transformation from a closed circuit system to an open space system.This paper presents a general circuit model unifying the exciting sources and loaded networks.Furthermore

the interaction of circuits and fields is unified in the generalized matrix Ohm's law that is given in this paper.It is shown that the sources or load networks

as the circuits

produce coupling to the antenna or scattering bodies so they affect the near fields and radiated pattern.
