Standing Waves in Systems of Perturbed Sine-Gordon Equations

摘要

Systems of 2D perturbed Sine-Gordon equations are solved numerically by a leapfrog difference scheme. OpenMP parallel programm is realized and tested on the computational cluster of IICT-BAS. As a result a clear three-dimensional standing wave pattern is seen for certain parameters. This result agrees with previous studies of other authors. The observed numerical solutions well explain the experiments on powerful THz radiations from mesas of BSCCO crystals.
