Lorentz force is introduced by Maxwell electromagnetism theory to reflect the influence of external magnetic field on elastic wave propagation.The generalized thermo-elastic GN(Ⅱ)model is applied to reflect the influence of thermo-mechanical coupling effect on elastic wave propagation.The influence of external magnetic field and thermo-mechanical coupling effect on the wave mode and dispersion characteristics is analyzed by the dispersion equation and the phase velocity.The energy flux ratios of various reflected waves and transmitted waves to incident waves are calculated by using the continuous boundary conditions.Finally,the reliability of the numerical calculation results is verified by the normal energy conservation.
