After a career of 63 years studying
electromagnetism, Catt talks at more than one level.

Skipping to and from between levels is unhelpful,
particularly if questions are confused with theory. A question is not a theory.

**1.** **Within the framework of classical
electromagnetism, with questions. Classical theory is not in doubt. These are
merely enquiries about details in that theory.** 1 http://www.ivorcatt.co.uk/cattq.htm
. 2 When a TEM step travels along a
transmission line at the speed of light, http://www.ivorcatt.co.uk/cattq.htm
, does the vertical line in http://www.ivorcatt.co.uk/x22j.pdf
involve displacement current, and does it cause magnetic field? If so, is this
field in the horizontal plane? 3. Can we send two pulses in opposite
directions in a coaxiaL cable to pass through each
other? When two pulses travel through each other in a coaxial cable so that the
electric currents are cancelling, and there is no net electric current,
following Oersted, what causes the magnetic fields in the pulses? Or do the
magnetic fields disappear and reappear once the pulses have left each other? Or
can we have two electric currents travelling though each other in opposite
directions in a single conductor, each generating their own magnetic field? Is
Professor Howie right to say there are “ohmic losses” when the total electric
current is zero?

It will be very helpful if Professor Kiehn comments on any of the above.

**2.** **New information, still within classical
theory.** 1 When electricity enters a capacitor, it first has
to spread out across the capacitor plate. http://www.ivorcatt.com/3613.htm

This has been overlooked, even by Heaviside, for 150 years. 2. When a signal travels down a conductor in a printed
circuit board in the presence of a second conductor, there are two velocities
involved. http://www.ivorcatt.co.uk/x0305.htm
3. Maxwell’s Equations. Maxwell’s Equations
revisited. http://www.ivorcatt.org/icrwiworld80mar1.htm
. Also The Hidden Message in Maxwell’s Equations. http://www.wbabin.net/historical/catt4.pdf
. This was an extraordinary discovery. The Emperor had no clothes. The amount
of information about electromagnetism in Maxwell’s Equations was minimal. This
leads us to an oversight which makes the equations look to have more substance
than they really have. 4. The Sign of Time. http://www.forrestbishop.4t.com/EMTV1/EMTvol1p112-3.jpg

**3.** **New theory.** 1. (Perhaps
still within classical theory.) http://ivorcatt.co.uk/x212.pdf .
When a charged coaxial cable is discharged, what comes out is half voltage and
double length, indicating that the “steady charged capacitor” was not steady,
but had energy vacillating from end to end. 2. Self
resonant frequency does not exist in a capacitor. http://www.ivorcatt.co.uk/26031.htm
3. A stationary electric field and a stationary
magnetic field do not exist. The only thing which exists is an electromagnetic
field ExH travelling at the speed of light. Any
apparently steady field is the superposition of two such electromagnetic
fields. 4.This is the historic advance, similar
in importance to the removal of caloric or phlogiston. Theory C. When a battery
lights a lamp, electricity is not involved in the transfer of energy. Electric
charge and electric current are mathematical manipulations at the edge of an
electromagnetic field. The equations used are Maxwell’s Equations.

This is not comprehensive, but merely
illustrates the opportunity for confusion.
