In this paper, the symmetries and Lie algebra of a coupled nonlinear waveequation were discussed. One-parameter transformation groups of this equation were obtained by using the symmetries.
From plasma wave equations and plasma kinetic equation, we analytically discussed the characteristic of current in an inductive coupled RF plasma and their damping mechanism.
