摘要
本文将互能公式应用到平面波展开理论中,讨论了传输波与凋落波在正交性方面的区别,得出了电流分布已知时场的平面波展开公式。本文还解决了一个由已知区域部分边界上的切向场决定区域内场的问题。
Mutual energy formula is used in the theory of expansion of radiation field in plane waves. The differences of transmissive wave and evanescent wave in orthogonality are discussed. The formula for expansion of plane waves with a known current distribution has been given. A problem to determine the inner field of an area in which the tangential fields' of partial border have been known has been solved.
