I've been looking at the MFIE equations for solving EM scattering
problems and I suspect I must have missed something. I'd be grateful
if someone could point out what....
Taking the MFIE euation as:

Now magnetism has been renamed "the lorenz force" have a look ant my web

I have a 1mW 400MHz transmitter that needs to operate inside of a very
strong electromagnetic field operating at 80kHz.  The 80kHz field is
emitted from a large (1.5' dia) coil with 2000V P-P across it.  When I
place the 400MHz transmitter (doing a CW) inside the center of the

My EM book discusses TE, TM, TEM solutions to the wave equation in a
parallel plate wave guide and I was wondering what determines the mode a
wave travels in.  While I understand that mode effectively determines a
cutoff frequency for propagation and evanescence - in addition to ...

I am trying to model a transmission line for a particular length as a
lumped LC model using SPICE, when i place a voltmeter against a
terminating resistance at the far end , i get a good response but if i
place a voltmeter at the near end or anywhere else along the line, the

I was just working through a derivation for reflection & refraction of plane
waves from a surface.  It appears that there are two versions of the
reflection & transmission coefficients, one for parallel and perpendicular.
During the derivation, it appears that snell's law and the ...

I was just flipping though my old EM book and have noticed that all examples
of EM plane wave reflection was for normal incidence - boundary conditions
trivial.  I was wondering how to compute reflected and refracted waves if
the incidence angle isn't normal.

A paper on the subject shows that, contrary to the standard field
theory, a mirror reflecting a circularly polarized plane wave receives
spin. The paper is published at www.mai.ru/projects/mai_works/ and
www.sciprint.org/. Unfortunately, it was rejected four times by Opt.

I think in classical electrodynamics from the Maxwell's equations it
was following that the phase change of an EM wave by the reflection on
the boundary between two media is 180 grad or PI rad (and it doesn't
depend on the incidence angle or the transmission rate). But for a beam

Dear Group---Thanks for your opinions. What I really need help with is
a simple understanding of magnetic force in one short paragraph.  I
have been told that the force is due to virtual photons.  But I can't
visualize how they do that.  Also I would like to know the wavelength

In the past several months there has come a change over me and I wish
to note it here and now. I have found out what all of this Internet
postings is coming to. It is a rough draft of what I eventually will
put all into print publication. One of the items I need to have in
