The present paper is concerned with the propagation of waves in microstretch thermoelastic solid with microtemperatures. The phase velocity, attenuation coefficient, penetration depth and specific loss of longitudinal displacement wave, thermal wave, microstretch wave, longitudinal microtemperature wave, coupled transverse displacement wave, microrotational wave, transverse microtemperature wave are obtained. Microstretch, microtemperatures and microrotational effects on the phase velocity, attenuation coefficient, penetration depth and specific loss have been evaluated numerically and presented graphically. Some special cases of interest are also shown.
