The present investigation deals with the study of plane waves and fundamental
solution in a modified couple stress generalized thermoelastic solid with mass diffusion. It is
found that for two-dimensional model, there exists three longitudinal waves namely
Longitudinal wave (P-wave), thermal wave (T- wave), mass diffusion wave (MD-wave) and a
set of coupled transverse waves (SV1 and SV2 waves). The phase velocity, attenuation
coefficient, specific loss and penetration depth are computed numerically and presented
graphically. The fundamental solution for the system of differential equations for steady
oscillations in terms of elementary functions has been constructed. Some properties of
fundamental solution are also established. Various particular cases of interest are also deduced
from the present investigations and compared with the known results.
