In this work, a generalized model on plasma, thermal and elastic waves was used to study the wave propagation of semiconducting material during the photo-thermal process. The thermal relaxation time, the coupling between the plasma, thermal, and elastic waves has been considered. The analytical solutions in the transformed domain by the eigenvalue approach have been obtained based on the techniques ... Read more

In the present work, the coupled plasma theory (thermally and elasticity waves) was used to study the wave propagation of semiconducting sample through photothermal process. The coupled of the plasma, thermally, and elastic waves that photo-generated through intensity modulated laser beam and tightly focused has been considered to study an elastic homogeneous semiconducting medium with isotropic thermo-elastic properties. Laplace transformations ... Read more
