Hyperbolic-Tangent Shocks in a Lossy Nonlinear Transmission Line
Eugene Kogan
We solve exactly the inverse problem for traveling fronts in a lossy nonlinear transmission line. Starting from a prescribed hyperbolic-tangent profile, we determine the voltage--c…

On the kinks in discrete systems
Eugene Kogan
We use perturbation theory to study kinks in nonlinear Klein--Gordon ( and sine-Gordon) chains and in a discrete series-connected Josephson transmission line. The expansion p…

Shock waves in nonlinear transmission lines
Eugene Kogan
In the first half of the paper we consider interaction between the small amplitude travelling waves ("sound") and the shock waves in the transmission line containing both nonlinear…
