The reflection of plane waves at the free surface of transversely isotropic micropolar viscothermoelastic medium is investigated. It is found that there exist four types of plane waves in transversely isotropic micropolar viscothermoelastic medium, namely quasi-longtitudinal displacement (qLD), quasi-transverse displacement (qTD), quasitransverse microrotaional (qTM), quasi-thermal (qT) wave. The amplitude ratios corresponding to reflected waves are obtained numerically when different waves are incident. Numerically simulated results are depicted graphically with respect to the frequency. The effect of viscosity on the amplitude ratios are shown graphically for specific model. Some particular results are also deduced.
