when you supply equations that predict something DIFFERENT than
Maxwell please let me know, otherwise i need no snake oil.

p.s. talking energy when trying to figure out what happens with waves
is counterproductive. energy is an integration of power, power is a
function of current or voltage and impedance, or field strength and
impedance of the medium... when you go from fields or current/voltage
to power you lose phase information that is important. integrating it
into energy loses even the phase and time information. it is always
best to describe waves by using one field or the other, which one is
up to the student since they are always related by the impedance of
the medium... the same goes for currents or voltages on conductors,
pick one and stick with it, you can always calculate the other when
needed.
