What Materials Are Used in Nonlinear Transmission Lines?

[Jdo300]

Hello All,

I was doing some *basic* reading about nonlinear transmission lines and I was wondering what people make them out of? Is there a special nonlinear material that is used or does one simply use copper wire and caps and inductors? would it be possible to make one using simple coax cable since I imagine that one could create variances in capacitance by putting a signal through the outer wire mesh. Maybe not. Any thughts?

Thanks,
Jason O
