The present study is focused on devoting a model to estimate the response of impedance parameters in micropolar with modified Green-Lindsay (MMGL) generalized thermoelastic medium. The problem of reflection phenomena is formulated and explained for the considered model. Amplitude ratios of various waves are obtained for the MMGL model, Green-Lindsay (G-L,1972) thermoelastic model, and Lord-Shulman (L-S,1967) thermoelastic model for longitudinal displacement wave (LD-wave), thermal wave (T-wave), coupled transverse (CD-I) wave and coupled micro-rotational (CD-II) wave. These amplitude ratios are the functions of the angle of incidence, frequency, and impedance parameters. The impact of impedance parameters on various reflection coefficients is displayed in the form of a graph. From the present study, certain cases are also deduced.
