Waves are useful. However, they are not living objects. They have no

All EM waves must obey the conservation of energy and
conservation of momentum principles. It is not a will
to survive - it is simply the laws of physics.

Here is an example for you to explain. The source is
a signal generator equipped with an ideal circulator
and a load resistor:

Steady-state #1: Rho at '+' equals 0.7143. Load equals
300 ohms.

100w SGCL--50 ohm feedline--+--1/2WL 300 ohm feedline--300 ohm load
Pfor1=100w-- Pfor2=49w--
--Pref1=51w --Pref2=0w

Pref1 is an 51w EM wave whose energy and momentum must be
conserved.

Steady-state #2: Rho at '+' equals 0.7143. Load is switched
to 50 ohms.

100w SGCL--50 ohm feedline--+--1/2WL 300 ohm feedline--50 ohm load
Pfor1=100w-- Pfor2=204W--
--Pref1=0w --Pref2=104w

*Note that Rho has NOT changed!*

The only question that you need to answer is during the
process that changes Pref1 from 51 joules/sec in the direction
of the source to 0 joules/sec (canceled), *exactly* what happens
to the energy and momentum? Please be specific.

You first.

Cop out. Why am I not surprised that you, yet once again, refuse
to answer the question? Could it be because you would immediately
be proven wrong? Do you really believe that diversions are a tool
of technical knowledge?

The original 51 joule/sec reflected wave toward the source interacts
with the newly reflected wave from the load and is partially
canceled which through constructive interference, delivers more
forward power toward the load, which results in an increase in the
energy in the reflected wave from the load, which results in more
wave cancellation at '+', etc. until steady-state #2 is reached.
