A nonlinear transmission line
is a form of artificial transmission line formed of a periodic structure
of series inductors and shunt capacitors. In this case, the capacitors
are sensitive to voltage, for examples, varactors
or BST capacitors could be used.
For nonlinear transmission lines,
the acronym is NLT or NLTL
(take your pick!)
When a voltage waveform travels
along the NLT it is distorted, usually the waveform becomes sharper
(faster transition times). One application of NLT is a comb generator.
