Dispersive Equation of Rayleigh Guided Wave

Guided waves had been studied for a long time. However, most of all were the kind of Love. And the studying of Rayleigh guided waves are not enough. Rayleigh guided waves which have two components are more complicated than Love guided waves that have only one component. This paper started from elastic theorem, derived the dispersive equation due to the idea model. And through programming computing, the dispersive characters of symmetry and dissymmetry models are obtained, which made some theorem basis for using Rayleigh guided waves in coal field.
