Abstrakt: The homogeneous isotropic micropolar porous thermoelastic plate under memory-dependent derivatives (MDD) has been taken into consideration to investigate the wave propagation regarding Lord-Shulman (LS) and Green-Lindsay (GL) theories. The governing equations are non-dimensionalized and solved using normal mode analysis. The dispersion equations for both symmetric and anti-symmetric modes of wave propagation are obtained in the assumed model. The comparisons between the variation of phase velocity and attenuation coefficient corresponding to LS and GL theories are shown graphically using MATLAB software. The amplitudes of dilatation, volume fraction, micro-rotation and temperature distribution are computed analytically and presented in the form of graphs for LS and GL theories in the presence of MDD. Various particular cases are discussed in detail. [ABSTRACT FROM AUTHOR]
