i JUST HAD A LOok @ the resonant cavity one .
A yes , the bessel function , I knew tubes followed that function .
Nicely illustrated , dam this stuff is hard but this is where the secrets lie hidden . The images and the formulas can help understand the directions of everything.
Yes, Dankie This is pretty hard stuff.
Too much info in those pdfs, but all has connections.
What I find very interesting is how stan build his cavity's.
Looks like he used specific dimensions for them to operate on resonance between dipoles. See picture Don posted of res.cav.
It has special effect when AC is used on it. A cavity acts as a capacitor like a inductor and resistor on particular frequencies. Just like a LCR circuit if dimensions and frequencies are matched.
Feel free to post more on this subject...or...the others...
