The above are the two key pictures, deriving from http://www.ivorcatt.co.uk/x0307.htm and http://www.ivorcatt.co.uk/x0357.htm


What is proven is that at one point in space there are two electric field densities and directions, and also two magnetic field densities and directions. This is totally revolutionary, and I should have noticed it 46 years ago. Dave Walton on the phone today confirms that he did not notice this either. The two fields are derived using Faraday's Law, and proven mathematically by me in my paper "Crossstalk (Noise) in Digital Systems, which can be reached at

http://www.ivorcatt.co.uk/x0305.htm . In that paper I then (wrongly) assume that superposition is permissible, and I show superposition at http://www.ivorcatt.org/digihwdesignp57.htm . But

Faraday's Law does not permit superposition. You cannot have two changing magnetic fluxes through the same surface causing two different voltages around the periphery of the loop. Under conventional theory, you cannot have two electric fields or two magnetic fields at one point in space at the same instant in time.


Then I realised that we already had this many years ago when we went two pulses from opposite directions down a coax, when they overlap. However, the case from crosstalk, http://www.ivorcatt.co.uk/x0362.jpg , when both travel in the same direction, is more grotesque (under classical theory). In contrast, Theory C makes no assertions for or against over this.
