But the incident and reflected components of the magnetic field don't.
Is that cool or what?

It's simply another example of the conservation of
energy principle in action.

Yes. When a radio wave encounters a short-circuit, a reflection takes
place with reversal in phase of the voltage but with no change in phase
of the current. Voltage cancels and current doubles at the
short-circuit. Reflection reverses the wave`s direction of travel
because only one of the wave`s components has had a phase reversal but
not both. Sinultaneously reversing the phase of both wave components has
no effect on the direction of wave travel.
