Default what happens to reflected energy ?

Laser light can usually be considered to be coherent light as are

perfect.

Radio waves and the light photons flow directly through the dielectric layer
of a capacitor.


Energy flow, just not as "current".

Electrons are compressed in the ends of the open circuit (condenser and
antenna).


"Compressed" may be overstating the phenomenon. Have you ever
calculated exactly how far an electron moves at 10 MHz?

Electrons are simple.


Yes, too simple to move at the speed of light.

No. People produce the coherent light in :

Each waves transports the mass and energy.

Electro gas behaves like all gases.

Air particles move with the speed temperature dependent.
Electrons do the same.

you can do better than that, you just aren't being any fun now!

I do my best.

May be the Wiki is better: "The electron temperature of a plasma can be
several orders of magnitude higher than the temperature of the neutral
species or of the ions. This is a result of two facts. Firstly, many plasma
sources heat the electrons more strongly than the ions. Secondly, atoms and
ions are much heavier than electrons, and energy transfer in a two-body
collision is much more efficient if the masses are similar."

You know: The Sun produces the plasma (it rotate with the Sun) and the
plasma is a medium for the longitudinal electric waves (Tesla - the father
of the radio). Is not it funny?

You say lasers are not coherent and then post the url containing

Free electron laser it is a quite different thing than laser.

The free electron laser produces the "laser-like" light:

" As the electrons are undergoing acceleration they radiate electromagnetic
energy in their flight direction, and as they interact with the light
already emitted, photons along its line are emitted in phase, resulting in a
"laser-like" monocromatic and coherent beam". From:
http://en.wikipedia.org/wiki/Halbach_array

When is a laser not a laser? When it is a free electron laser.
Unfortunately, I understand completely.

Sorry, just my feeble attempt at some comic relief. Guess I should

Laser = "laser - an acronym for light amplification by stimulated emission
of radiation"

Laser rework natural light (radiation).

Antennas produce artifical radiation in the result of the electron
oscillations.

To make the oscillations we use different devices.
LC for radio waves, megatrons for microwaves, claystrons for radar waves and
the Halbach array for the light frequency.

The word "laser" is probably common name for the all atificical light
sources.
