电磁驻波中的能量与能流分布探讨

摘要

本文对平面时谐电磁波形成的驻波能量与能流的分布情况进行了理论推导,探讨了电磁驻波能量的分布特征.结果与机械波形成的驻波场进行比较,揭示了驻波能量和能流的规律具有普遍性.%In this article,theoretical derivations were carried out to reveal the distribution of energy and energy flow of the plan harmonic electromagnetic standing waves.The distribution properties of the standing wave energy are discussed in detail.It was found that the forms of electromagnetic wave distributions are in consistent with the standing wave generated from the mechanical wave field,which reveals the law of standing wave energy and energy flow is universal.
