Re: Circularly polarized beam in a dielectric, etc.



The Beth experiment was intensively discussed at this page. So, I
inform you that I have posted a new paper "Paradox of the classical
Beth optics experiment" at www.sciprint.
I show that the celebrated Beth's experiment contradicts the angular
momentum conservation law in the frame of Maxwell electrodynamics
because Beth's birefringent plate experienced a torque without an
angular momentum flux in the surrounding space. However, this paradox
can be removed by introducing a classical spin tensor.
At the same time I submitted this paper to Journal of Optics A: Pure
and Applied Optics through IOP.

We calculate absorption of a circularly polarized light beam in a
dielectric in the frame of the standard electrodynamics. A transfer of
energy, momentum, and angular momentum from the beam to the dielectric
is calculated. The calculation shows that the angular momentum flux in
the beam equals to two power of the beam divided by frequency. This
No its just P/w for circular polarised light. Not 2P/w !
Analogon: Energy of photon hbar w, Spin = Energy / w for circular
polarized
photons.
P/w is for a plane wave, but 2P/w is for a beam

2 P/w how that ?
Quote: 
And also note: Natural light has spin zero !
That's not the point
result contradicts another part of the electrodynamics, which predicts
the flux equals to power of the beam divided by frequency. In addition

for circular polarized light only or ?

Dear Josef, I taught you many times that they used a wrong formula
spin=ExA.
If E=exp[i(zt)], A=iE, and spin=Re(ExA*)/2 =Re(iExE*)/2 =Im(ExE*)/2.
This formula is presented by Timo et al. in Nature 394, 348 (1998), and
physics/0408080 with small mistakes.
This formula is wrong because ExA is a component of the wrong canonical
spin tensor. Physicists eliminate this tensor by the use of the wrong
BelinfanteRosenfeld procedure. I wrote about this many times, see
Measurement Techniques, 46, No. 4, 317 (2003), or www.sciprint.org.

Yes and E x A is zero in the time average isnt it ? But the formula of timo
i speak of
is a E x E* and a purely imaginary number. Thats Timo also.
And i remember a discussion with you short time ago that you  and not
Timo 
said that E x A is the right spin tensor, isnt it ?
E x A obviously is wrong !

Sorry, I cannot understand your thought. Please say it in other words
In an dielctric that is not absorbing they are perpendicular exactly.
This is not exactly. E may be parallel to H even in vacuum. Please use
the superposition principle and sum two plane waves in vacuum:
\vec E_1=(\vec x+i\vec y)exp[i(zt)], \vec H_1=(i\vec x+\vec
y)exp[i(zt)]
and
\vec E_2= (\vec xi\vec y)exp[i(zt)], \vec H_2=(i\vec x\vec
y)exp[i(zt)].
These notations mean: E_{1x}= exp[i(zt)], E_{1y}=i exp[i(zt)],
H_{1x}=i exp[i(zt)], etc.
You will get E is parallel to H.
Please read physics/0102084, as the minimum.

Superposition principles  interesting thing. An infall wave and reflected
outfall wave is indeed
not zero flux for infall and outfall. But the resulting flux is zero i
agree.
Thus int r x S(total) is zero obviously.
Your example is a example that is not good because if at all a very special
case to add fields and
using trigonometric relations for the cos and sin of the sum and difference
of two angles. I have not
proven if everywhere everytime resulting E and H are parallel. This
treatment would be one connected
with what is called standing wave. That could be right. But i think there
are further conditions necessary
to form standing waves as for example a exact parallel boundary within the
light emitting source or
similar things. The normal back  reflection at small angles of incidence
towards the source does not have
standing waves involved. And i think Beths experiment does not have standing
waves and brings
probably almost same result at small angles of incidence or ?
I have also a nice contribution to superposition principles in metals.
Superposition of fields is wrong in
general complex situations.
The energy flux for E and H waves must be calculated seperately from each
other.
So you have two superposition principles. And a third flux, the tunnel flux
must be calculated seperately.
This flux is the dominant 100% flux in the gap of Nimtz double prism
experiment. The tunneling flux results from mixture of reflected and infall
wave. Just that you see that superposition is nothing new to me.
Quote:

The virtue of my spin tensor is it provides for spin flux without
energy flux. I wrote about the Beth experiment, "Thus, the total

equal to 4 in the absenceof an energy flux!" [Measurement Techniques,

flux=rx(ExH) does not contain spin in the sense of the word as used in
the field theory. The Humblet et al. procedure leads to the senseless

This is just the same formula for spin that appears in Crichton or (iirc)
