人们对天线如何辐射以及其辐射源在哪里这一基本问题非常感兴趣。大多数检查都集中在追踪天线上的“辐射中心”。本文的目的是展示如何确定静态和无功能量转换成辐射在天线周围的领域。辐射的起源在定性的基础上得到了很好的理解。为了更准确地回答这个问题，作者提出了一种分析电磁能如何表现的新技术，称为“因果表面”方法。
There is great interest in the fundamental question of how an antenna radiates and where is the source of its radiation. Most examinations have focused on tracing radiation back to "radiation centers" on an antenna. The aim of this paper is to show how to determine where static and reactive energies are converted into radiation in the fields around an antenna. The origin of radiation is well understood on a qualitative basis. To answer the question more precisely, the authors present a new technique for analysing how electromagnetic energy behaves, called the method of "causal surfaces".
