| 摘 要： | We study the nonlinear solitary wave solution under the transverse perturbations for a system of coupled nonlinear electrical transmission lines.In the continuum limit and suitably scaled coordinates,the voltage on the system is described by a modified Zakharov-Kuznetsov equation.The cut-off frequency of the growth rate for the solitary waves under transverse perturbations has been analytically obtained.It is in agreement with the cases P=1/2 and p=1 which have been studied previously.
