RE: The great and silly transmission line debate
I agree that is what we should be debating. How would you estimate the
effective R and the Q factor at the design stage? Then how would you test
for these two parameters after the TC is built to determine how well you did
with your estimate?

In order to prevent another of those embarrassing debates
between the 'alternative' lumped and transmission line
------------------- big snip
I will add this: effective methods are available to estimate
the equivalent C to go with the solenoid's L. The same is not
true of the R. There is no currently accepted theory which can
give a value of effective R for a given coil geometry. Some
empirical work has led to tables which estimate R but these only
work up to, but not including the lowest resonant frequency.
Thus it is still not possible to predict the Q factor or input
impedance of a tesla resonator, even after a century of use!
But thats another subject, perhaps the one we should be debating!
