Microwave circuit electrodynamics of disordered superconductors is a very active research topic spawning wide range experiments and applications. For compact superconducting elements, the transition to an insulating state poses limit maximum attainable kinetic inductance. It is, therefore, vital study fundamental noise properties thin films close this transition, particularly in situations wher...

In this article the symmetries of a class of nonlinear telegraph equations are examined. These equations represent a physical model describing electro magnetic shock waves. The main interest is concentrated on potential symmetries but Lie point and non classical symmetries are also calculated. With the aid of these symmetries explicit new solutions are derived or given implicitly by defining eq...

Differential quadrature method DQM is proposed for the numerical solution of oneand twospace dimensional hyperbolic telegraph equation subject to appropriate initial and boundary conditions. Both polynomial-based differential quadrature PDQ and Fourier-based differential quadrature FDQ are used in space directions while PDQ is made use of in time direction. Numerical solution is obtained by usi...
