Abstract
Present article is concerned with the propagation of plane waves in a nonlocal, microstretch thermoelastic half-space with temperature dependent properties. Five basic waves consisting of three sets of coupled longitudinal waves and two sets of coupled transverse waves travel with distinct speeds in the considered medium. The numerical values of amplitude ratios are shown graphically to explore the effects of temperature dependent properties, nonlocal and microstretch parameters. The effect of nonlocality on the phase speeds and attenuation coefficients of propagating waves have also been observed. It has also been verified that there is no dissipation of energy during reflection phenomenon.
