Reflection and transmission of an incident plane transverse wave at a plane interface between two dissimilar generalized porous thermo-elastic solid half spaces is analyzed. The theory of generalized thermo-elastic material with voids in the context of Lord–Shulman theory has been employed to set down the equations of motion and constitutive relations. The reflection and transmission coefficients for a transverse wave incident at a plane interface have been derived. Partition of energy at the interface has also been considered together with the law of balance of energy.
