what happens to reflected energy ?

Nope, I believe you are only a figment of my imagination. Please prove
that you actually exist.
I suppose, but then you have to give up on P(t)=V(t)*I(t), generally
considered to be a rather fundamental equation.
I have absolutely no problem with giving up on the conservation of
power principle in which no rational technical person can possibly
believe.
Are you saying that conservation of energy only applies some of
the time?
No, I am saying that if you cannot balance the energy equation at all
times, you have made a mistake. You are not tracking joules. You are
attempting to track watts which can appear and disappear at any time.
The only condition where watts can be tracked is over an integer
multiple of complete cycles. That's why watts can be tracked when the
frequency is in the MHz. Trying to track instantaneous watts within a
fraction of a cycle is a moronic attempt at power superposition, a no-
no that we all learned in EE101.
In your example, the RF energy does seem to disappear and re-appear,
when tracked on a moment by moment basis.
No, the power can disappear and re-appear but the energy cannot. You
have not even come close to tracking the energy.
Well, it would help if you could actually find and articulate a flaw
inhttp://sites.google.com/site/keithdysart/radio6.
The flaw is your belief in a conservation of power principle that
doesn't exist. Instantaneous power is not required to obey any
conservation principle. What you are doing on that web page is
attempting to superpose powers apparently without a clue.
Superposition of power is a no-no. The power density equation allows
us to accomplish the addition of *average* powers taking interference
into effect. I know of no such mathematical equations for
instantaneous power and your instantaneous power superposition
technique is obviously invalid.
