ABSTRACT:
Usually, electromagnetic
evanescent waves are some kinds of near fields. However, it looks as if the
evanescent waves inside a cut-off waveguide had nothing to do with any near
field. In this paper, we will show that the evanescent waves inside a cut-off
waveguide can also be regarded as the near fields of an aerial array.
