Re: [TCML] Wireless Transmission Theory

Hi Ed,

No, it hasn't been useful at all. I've read it a couple times but it's a 
lot of math and simply a method to pull in and account for the 
distribution of current and voltage along a helix at the fundamental. 
It's simply another method to do this. The Corum's make many statements 
throughout the document that lumped element analysis assumes a DC 
distribution and they argue that the current is non-uniform. Well, they 
are correct that the current is non-uniform (except when the helix is 
short). The problem is their analysis of lumped circuit theory which I 
think is because rarely is the non-uniform characteristic looked at. 
Paul Nicholson has shown and argued the non-uniform distribution for 
years and quantifies the coil without the need of wave propagation 
analysis. The fact is, the non-uniform distribution characteristics can 
be modeled with lumped circuit theory (Paul's software does this and 
Javatc does this as well which as Kurt mentioned, is a bi-product of the 
TSSP).

I realize the Corum's bias and I don't disagree with their basic 
statements on current distribution. I do disagree with their statements 
about lumped circuit theory (note they never once explain, they simply 
make a blanket statements throughout the document).

If anyone is ever curious about how Paul's software or even Javatc and 
Fantc perform their functions, you need only to read the following:
http://www.abelian.demon.co.uk/tssp/pn2511.pdf.zip
http://www.abelian.demon.co.uk/tssp/pn1401.pdf.zip

These are still works in process, but explain well what is happening in 
the resonator of coils. When it comes to Tesla Coil physics, this is the 
best I'm aware of that deals with the Tesla Coils we build.

Take care,
Bart
