Reflection and transmission phenomenon due to a set of coupled dilatational waves incident obliquely at a plane interface between two different magneto-elastic half-spaces containing voids has been investigated. Using suitable boundary conditions, the equations providing the reflection and transmission coefficients corresponding to various reflected and transmitted waves are presented. Some new/earlier known results have been deduced from the present formulation. The effect of induced electric field due to applied magnetic field has been studied on the reflection and transmission coefficients. For a specific material, the amplitude ratios and corresponding energy ratios have been computed numerically and depicted graphically against the angle of incidence and frequency. The effects of various parameters have been noticed.
