Stan uses a square wave *in resonance* , its like if you had a resonant filter .
Thus a sine wave .
I dont know why a sine wave should be used , its just cool I guess .
Transformers love sine waves . You cant run a television set witha square wave inverter , it gives glitches , you cant run a motor with square AC , it loves the pregression of the sine . Radio waves dont penetrate matter with square AC , the best penetrator is the sine ...
I just some compkicated electrical physics physics , fast rise + impedance mismatch = reflexion .
Stan was a radar techician remember and he , he would be a master at these short pulses pulses , I bet he could solve these issues that we can barely understand , it really is a specialised field . Thats what happens with radars, they use square cause it bounces bakc instantly .
if you physically bend the coax cable not smoothly enough you get reflecion , bends on coax are real smooth for minimal reflection , electricity is more than just flow of current etc ,..
