Szukana fraza: [Abstract = "The objective of the paper is to look at the propagation and reflection of plane waves in a thermo\-diffusion isotropic medium. The reflection of plane waves in a thermo\-diffusion medium was investigated in this study with reference to triple phase lag thermo\-elasticity. The memory dependent derivative \(MDD\) is applied for this investigation. The fundamental equations are framed and solved for a particular plane."]
