| Abstract |
In this research, the nonlocal thermo-elasticity theory in the context of fractional order time derivative three phase lag model is employed to explore the reflection of waves in a micro-polar semiconducting medium with voids. Two dispersion relations for speed-frequency are computed, corresponding to longitudinal and transverse waves. The dilatational waves are affected by voids, thermal, and nonlocal factors, whereas transverse waves are mainly influenced by nonlocality and micro-polarity. Analytically, reflection coefficients and their related energy ratios are computed. For a specific material, Silicon, the findings are analyzed visually. In addition to semiconductor nanoparticle systems, the research might be beneficial for semiconductor nanostructure, geology, and seismology. |
