摘要
本文从·E=0及×E=iωμH两式出发,无须解出波导管内电磁场的各个分量或横向分量与纵向分量的关系,即可证明波导管内不能传播TEM型电磁波,并从物理概念出发给出一个更简捷的唯象说明。
In this paper we use both ·E=0 and × E= lWμH directly to prove the fact that the transverse electromagnetic wave can't exist Inside a waveguide tube and thus without any need to solve the components of electromagnetic field or the relation between the transverse components and longitudinal component, and therefore a phenomenologlcal explanation may be given with the suggestion of physical concept.
