Evanescent Fields inside a Cut-off Waveguide as Near Fields

Abstract

<p> <span>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.</span> </p

General Classical Electrodynamics

“…Superluminal evanescent 'tunneling' of fields has been reported [24]. Usually such effects are explained as quantum effects, however, GCED-WP (a c) explains such effects as a Coulomb near field with superluminal speed, see also [25]. The authors of [26] experimentally proved that the Coulomb near field of a uniformly moving electron beam is rigidly carried by the beam itself, which is further described as follows: the Coulomb near field travels with velocity much greater than c. It is impossible to explain these results by means of MCED, since Jefimenko's electric field expression predicts a field retardation time interval of r/c for the electric near field and the electric far field.…”
