Numerical modeling of wave and oscillatory processes in active resonance transmission lines

We model numerically the processes in a one-dimensional model of an active nonlinear resonant medium. Allowance is made for a close coupling between the wave and oscillatory phenomena, variable structure of the fields, and a variable spectrum. The model represents a discrete transmission line with resonance circuits which contain nonlinear components. We solve the nonstationary equations of the system, and the voltage distribution is found by the driving method. We study a number of nonlinear processes, including the radiation of the active layer and a mutual synchronization of the autogenerators with a narrowing of the spectrum.
