Default what happens to reflected energy ?

So you now are in agreement that flows must balance if charge (or
energy) is to be conserved.


No, you remain confused and mistaken. Energy flows (de/dt) do NOT have
to balance. That's what I have been saying all along. Energy must
balance whether it is flowing and/or not flowing. I told you weeks ago
that the sum of your instantaneous energy flows do NOT include all the
energy, i.e. there is no such thing as conservation of instantaneous
power (energy flow). If you don't correct that basic misconception,
you will never get it.

The continuity equation aids my side of the argument, not yours. It
proves that you have been wrong all along when you did not include all
the energy in your instantaneous power equation.

Back to the LC oscillator. At the instant when all of the energy is
stored in the capacitor, energy flow has been completely destroyed,
i.e. de/dt=0, yet there is plenty of energy in the capacitor. Your
P(t)=V(t)*I(t) =0 equation completely ignores the energy in the
capacitor when I(t)=0 and I have told you all this many times before.
The continuity equation only highlights your error of ignoring the
stored energy.

After the rising edge goes by, which I assume you will still call an
EM wave, what follows until the falling edge occurs a year later?
Is it an EM wave?


If electrons (carriers) are not being accelerated and/or decelerated,
i.e. if DC steady-state exists, then there are no EM waves.
