The present investigation deals with the propagation of Rayleigh type surface waves in an isotropic microstretch thermoelastic diffusion solid half space under a layer of inviscid liquid. The secular equation for surface waves in compact form is derived after developing the mathematical model. The dispersion curves giving the phase velocity and attenuation coefficients with wave number are plotted graphically to depict the effect of an imperfect boundary alongwith the relaxation times in a microstretch thermoelastic diffusion solid half space under a homogeneous inviscid liquid layer for thermally insulated, impermeable boundaries and isothermal, isoconcentrated boundaries, respectively. In addition, normal velocity component is also plotted in the liquid layer. Several cases of interest under different conditions are also deduced and discussed.

The present article is aimed at an investigation of the propagation of elastothermodiffusive ETN surface waves in a homogenous isotropic, thermoelastic semiconductor material half-space underlying a viscous or inviscid fluid half-space or layer of finite thickness with varying temperature. The relaxation times of heat and charge carrier fields are also taken into consideration during the study. The secular equation that governs the propagation of elasto-thermodiffusive surface (interfacial) waves in the considered composite structures has been derived in compact form after obtaining the general wave solution of the model. Some particular forms of the general secular equation are also deduced and investigated. Numerical solution of secular equation and other relevant relations is carried out for silicon Si semiconductor material under different situations with the help of functional iteration numerical technique along with the irreducible case of Cardano's method. The computer-simulated results in respect of dispersion curves, attenuation coefficient, specific loss factor of energy dissipation and relative frequency shift due to loading are presented graphically to illustrate the analytical development. The results have been determined and compared with relevant publications available in the literature at appropriate stages of this work.

The aim of the present paper is to study the propagation of Lamb waves in micropolar generalized thermoelastic solids with two temperatures bordered with layers or half-spaces of inviscid liquid subjected to stress-free boundary conditions in the context of Green and Lindsay (G-L) theory. The secular equations for governing the symmetric and skew-symmetric leaky and nonleaky Lamb wave modes of propagation are derived. The computer simulated results with respect to phase velocity, attenuation coefficient, amplitudes of dilatation, microrotation vector and heat flux in case of symmetric and skew-symmetric modes have been depicted graphically. Moreover, some particular cases of interest have also been discussed.
