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.
