摘要:

New conservation laws are derived for free electromagnetic fields propagating into a half-space. Such fields can be represented by an angular spectrum of electromagnetic plane waves that contains only homogeneous plane waves. The similarity between some of these new conservation laws and the Poynting theorem is examined in detail.
