Evanescent Fields inside a Cut-off Waveguide as Near Fields ()
Affiliation(s)
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.
