摘要：

Emission of radiation (quasilinear waves) by a periodic array of moving kinks is investigated within the framework of a driven damped sine-Gordon model with the additional perturbing term F(x)sin. At first, radiative energy losses of a solitary kink are studied in detail; new emission-induced steps on the one-kink velocity-drive characteristic (VDC) are predicted. Next, interference of waves emitted by kinks belonging to a rarefied periodic array is considered. Emission-induced steps on the array-s VDC are described in detail. Emission of radiation by a densely packed array (represented by a nearly linear solution of the SG equation) is also considered, and the corresponding steps are described for random and periodic inhomogeneities. © 1990 The American Physical Society.
