REFLECTION OF WAVES IN TRANSVERSELY
ISOTROPIC MICROPOLAR THERMOELASTIC
HALF-SPACE
RAJNEESH KUMAR AND RAJANI RANI GUPTA

Abstract. In the present article, we discuss the problem of reflection of plane wave incident at the surface of transversely isotropic micropolar thermoelastic medium without energy dissipation. The wave equations are solved by imposing proper conditions on displacements, stresses and temperature distribution. It is found that there exist four different waves viz., quasi-longitudinal displacement (qLD) wave, quasi transverse displacement (qTD) wave, quasi transverse microrotational (qTM) wave and quasi thermal wave (qT). Amplitude ratio of these reflected waves are presented, when different waves are incident. Numerically simulated results have been depicted graphically for different angle of incidence with respect to frequency. Some special cases of interest also have been deduced from the present investigation.
