I don't remember saying that and I apologize if I ever did. What I
remember saying is that an RF standing wave doesn't meet the
definition of an EM wave which is essentially the same thing that Dr.
Hecht said: "Standing Waves:....These might better not be called waves
at all since they do not transport energy and momentum."

RF standing waves, unlike other EM waves, do not transport energy and
momentum at the speed of light in the medium. Therefore, they are
technically not EM (photonic) waves.
