It was an experiment in skin depth.

Strictly speaking the page describes a demonstration from page 321 of
this book:

G. Bekefi and A. H. Barrett, Electromagnetic Vibrations, Waves and
Radiation, (MIT Press, 1977)

A reviewer comments, "MITonline offers the course based on this book
for free. The course is great! This book is a less engaging, but a
more comprehensive version of A.P. French's original text for the
course. There are many gems in the book, such as insights into
microwave oven fundamentals, that are not present in basic texts.
Beware the softcover binding, it needs a gentle hand. "

What does the book point to, waves or particles? We all have plenty of
books and all cannot agree on the subject on radiation! In other words
they have placed their own interpretations of the observations seen
with the double slit experiment as over ruling of all and cast in
stone. This is what the physics forum sponsered by Scientific American
said to me as they banned me because of my temerety in challenging
their position.In addition they stated that it is not possible outside
the physcics spectrum to challenge anything which thus puts all in the
spectrum of crackpots. Dr Davis of MIT provided the mathematics
that confirmed the presense of particles, but mathematics was not
considered a reputable answer compared to the majority argument that
the mathematical aproach was illegal.
So waves hold the majority in the books but by its very presence all
understanding of radiation has been *stymied for the last hundred
years by the resistance to change without any accumpanying facts and
where physicists refuse to review to re examine what they state is now
"cast in stone." New books are written every year via plagarisation
for personal profit where the professor orders purchase of such books
for his pay off. Not one has come out with a review of radiation and
why progress has been stymied. And that goes for Radcom and QST who
have no real interest in advancing the hobby of its members.

Art,

The double slit experiment clearly points to particles or photons. The slits
are very narrow (otherwise the experiments don't work) and the wave like
properties are caused by the interaction of the particles with the atoms in
the walls of the slit as they pass through. The slit is modulating the
particles if you like.

We know that individual particles are involved because they can be counted
one by one through a detector.
We know that wave like properties are involved because of the effects
observed on a screen placed behind a diffraction grid.

The observed properties are due to influence exerted on the particles as
they pass through the diffraction grid by the atomic structure of the grid
itself. Unless the experiment were carried out at absolute zero, the atoms
in the walls of the slit are vibrating and must influence the photon as it
passes through.

At absolute zero, nothing would be moving, including the photon, so the
experiment collapses at this point.

Photons are particles that display wave like behaviour under particular
conditions.

Interesting video on the double slit experiment which reverses "waves"
back to "particles".
I wonder how long before the books are changed back to the thoughts of
Newton and possibly my proof with respect to particles? Its a shame
that the professors on the physics
forum are still in a pattern against change or just not up to date in
the absence of a new up to date book. Of course it will take much
longer for the ham community to reconcile themselves and it may take a
new generation to adjust.
And a bit longer for QST and Radcom as they have a back log of
articles with respect to soldering connections on coax, morse code key
design and push pull tubes used in radios!
I am extremely happy regarding the helical spin shown which I
determined as a scalar reaction to the rotation of the Earth as it
gives more credability to my position that it is one of the two forces
that make up the Standard Model.( see unwin antenna page) as well as
the notion of tipped verticles to reflect same
