Wave propagation in micropolar liquid-saturated porous solid

The present investigation is concerned with wave propagation in a liquid-saturated porous solid with micropolar elastic skeleton. Two different cases have been discussed - (i) Reflection of micropolar elastic waves at the free surface of a micropolar elastic liquid-saturated porous solid; and (ii) Propagation of Rayleigh waves in a micropolar elastic liquid-saturated porous solid. In case(i),the amplitude ratios for the different reflected waves have been calculated and presented graphically for different angles of emergence. Some special cases have been deduced. In case (ii), the frequency equation is derived and dispersion curves giving phase velocity as a function of frequency ratio and normalized wave number have been plotted graphically for a particular model.
