“The point about the Catt Anomaly has, says Ivor, nothing to do with his theory. It is an anomaly between rival textbooks and professors [Pepper and McEwan]. They will answer his polite query in their condescending authoritative manner until they are told that their ‘explanation’ is the exact opposite of that taken by other authors and professors . Then they cannot be induced to communicate with one another to resolve the problem.” – Editorial, Electronics World, August 2003, p3.

Catt has claimed that no academic
representative has ever replied in a satisfactory, written, public, manner to
his raising this question. In his own book [4], he cites several personal
communications. One is a 1993 letter by [Southerner] Sir Michael Pepper (born August 10, 1942), a renowned physicist active
in semiconductors. .... .... Besides some wrong explanations [e.g. Pepper’s, Lago’s and Morgenthaler’s Southerner answers] incompatible with Gauss’ Law,
most of the [Westerner] answers agreed in considering the problem not to be an
anomaly at all.
Pieraccini
omits to mention that Sir
Michael Pepper is incompatible with Gauss’s Law.

TEM TRANSMISSION LINES
An idealised uniform transmission line is comprised of
two or more perfect conductors that are parallel to one another and extend to
infinity without any change in their transverse geometries. In the simplest
cases, the conductors are surrounded by free-space and the guided electric and
magnetic fields are transverse to the direction of propagation and so denoted
TEM (transverse electric and magnetic).

.... the electric and magnetic fields are both zero
inside the conductors ....
.... It is tempting, but incorrect, to
conclude that the conductors merely provide a path for the charge distribution
to zip along at the speed of light, keeping pace with the generated fields. If
this were true, .... the charges would be traveling .... with incredibly large
energies. .... Yet somehow the individual charges .... .... act together to simulate a relativistic
current density .... .... Mobile negative charge which is neutralised by the
fixed positive charge of the lattice simply moves very slightly toward or away
from the surface of the conductor as the electric field of the TEM pulse moves by. [This is the Southerner view. – I Catt]

by. This creates the surface charges that are needed
in order to originate and terminate the electric field. As the pulse moves on
(at or near the speed of light), those charges move back into the metal and
different charges further down the line repeat the action to produce new
surface charge as required. [This is the Southerner view. – I Catt] Simply put,
the same charge does not travel with
the wave, but the distribution as a whole acts as if
it did. The macroscopic Maxwell Equations cannot, of course, distinguish
between the individual charges. .... If no (and consequently rho)
approach infinity, .... .... The result is dispersion-free propagation.

Professor M Pepper FRS on "The
Catt Question"
....
As the wave travels at light velocity, then charge supplied from outside
the system would have to travel at light velocity as well, which is
clearly impossible.
The answer is found by considering the nature of conduction in metals. Here
we have a lattice of positively charged atoms surrounded by a sea of free
electrons which can move in response to an electric field. This response can be
very rapid and results in a polarisation of charge at the
surface and through the metal.
....
August 23, 1993 Dear Raeto West, I write with reference to your letter of
August 19. Your description of the process is correct; as a TEM wave advances
so charge within the conductor is polarised and the disturbance propagates at right angles to the
direction of propagation of the wave .... .... Yours sincerely, M Pepper

Electromagnetism 1
by Ivor Catt
Westfields Press 1994
"The
main body of the text is devoted to transmssion lines
....
There
are numerous examples of sloppy argument in the text. .... The flaws in these
arguments are easy to see. ....
....
For
a vacuum dielectric the speed of the wavefront is the speed of light so that,
according to Catt, the charges on the conductors must travel at the speed of
light, which is impossible. This is the 'Catt anomaly'. Since the wavefront
does travel at the speed of light, so do the charges, which then have infinite
mass. It follows that there cannot be charges on the conductor surfaces and
conventional theory must be wrong.
The
flaw here is the assumption that the charges move with the wave. whereas in
reality they simply come to the surface as the wave passes, and when it has gone they recede into the conductor. [This is the Southerner
view. I Catt.] No individual charge moves with the
velocity of the wave. The charges come to the surface to help the wave go by
and then pass the task to other charges further along the line which are
already there and waiting. This is the mechanism of guidance and containement. There is no anomaly.
....
Catt's
belief in his own work is clearly sincere, but this reviewer, after lengthy and
careful consideration, can find virtually nothing of value in this book.

In the IEE/IET review of my book, The author Laso of http://www.ivorcatt.com/9_review.htm
actually gives one answer out of the two Establishment answers to the Catt
Question; the Pepper, or Southerner, answer. He is valuable, because the
Southerner answer is given by fewer luminaries than is the Westerner answer, so
Lago/IEE reinforces the minority (southerner) Pepper/ Morgenthaler stable, who defy Gauss’s
Law.]
