“…The problems of reflection and refraction of set of two coupled transverse waves and a set of two coupled longitudinal waves at a plane interface dividing a given medium into two half-spaces which are useful in engineering and geophysics areas. Many problems related to reflection and refraction of waves for a plane split into two media have been discussed by Tomar and Khurana [15]- [17], Tomar and Gogna [18,19], Parfitt and Eringen [20], Tomar [21], Singh et al [22], Zhang and coworkers [23]- [25], Achenbach [26], Sarkar and Tomar [27], Sahrawat et al [28] and Poonam et al [29]. Sahrawat et al [30] investigated the fundamental solution and plane wave propagation in nonlocal couple stress micropolar thermoelastic solid without energy dissipation.…”

The reflection and refraction phenomenon of propagation of waves in couple stress micropolar thermoviscous elastic solid media with independent viscoelastic and micropolar properties have been studied. The structure of the model has been taken such that the plane interface is divides the given media into two half spaces in perfect contact. Here, we find that there are five waves, one of them is propagating independently while others are set of two coupled waves travelling with different speeds. Energy ratios, reflection and refraction coefficients relative to numerous reflected and refracted waves have been investigated when set of two coupled longitudinal waves and set of two coupled transverse waves strike at the interface through the solid medium. The inequality of energy ratios, refraction coefficients and reflection coefficients are evaluated numerically and presented graphically under three theories of thermoelasticity, namely, Green-Lindsay theory (GL), Lord-Shulman theory (LS), Coupled theory (CT) versus angular frequency and angle of incidence.
