Resumen de P-waves reflection in a semiconducting photothermal diffusion medium with initial stress and magnetic field
In this paper, the main aim is estimation the effect of magnetic field, initial stress on reflection waves phenomena in a semiconductor photothermal diffusion medium considering Classical (CT) and dual-phase-lag (DPL) theories. The problem is formulated considering a generalized model for plasma, thermoelastic waves under thermomechanical response of a reflection of photothermal diffusion for semiconductor material. Maxwell’s equations are applied taking into account absence of displacement current and infinite conducting medium. The boundary conditions are applied for mechanical and Maxwell’s stresses, temperature gradient, chemical reaction, and diffusion on the interface adjacent to the vacuum. The reflection coefficient ratios have been obtained as functions of angle of incidence, magnetic field, initial stress, diffusion, photothermal, and semiconducting analytically and displayed graphically. A comparison has been made between the CT and DPL theories, as well as between the present results and the results obtained by others. The results of the present paper are a generalization of photothermal semiconductor medium and deduces to a special case if the new parameters are neglected. If the initial stress and magnetic field neglect, the results obtained in the current paper is deduces to the results obtained by others as a special case from this study.
