Rayleigh wave through half space semiconductor solid with temperature dependent properties

Abstract

he article focuses on Rayleigh wave propagation in a homogeneous isotropic semi conductor thermoelastic medium rotating with fixed angular frequency with temperature de pendent properties. The elastic constants depends upon the temperature function. The effects
of temperature dependency parameter and time derivative, fractional order are illustrated. By
the theory of thermo-elasticity, waves results in generation of thermal signals that propagate
through the medium. A heat conduction model of three phase lag (3PL) along with frac tional order time derivative is used to analyzed the thermal signals. The secular equations of
Rayleigh waves are derived mathematically at the stress-free, carrier density and thermally in sulated boundaries. Some specific properties like velocity, attenuation coefficient, specific heat
loss and penetration depth for Rayleigh waves have been evaluated and presented graphically.
The secular equations are computed numerically depicted graphically using Matlab.

Size-dependent effect on the interaction of surface waves in micropolar thermoelastic medium with dual pore connectivity

“…This comprehensive exploration of surface wave characteristics builds on the historical foundations laid by Lord Rayleigh and incorporates subsequent advancements in the field. Some recent literatures [7][8][9][10][11] investigated the propagation of plane and surface waves in layered structure.…”
