Default Constructive interference in radiowave propagation

All that may be true, Gene. But don't Maxwell's
equations obey the superposition principle?
What does Maxwell say happens when we superpose
two EM waves out of phase such that destructive
interference occurs? What does Maxwell say
about the energy "lost" to destructive
interference? Where did it go?

Are intensity calculations utterly inadequate
for exploring the details of low resolution
transmission lines? :-) If the intensity
(power) calculations enumerated in the s-
parameter analysis description are utterly
inadequate, why are they used so often?
