This paper introduces a novel theoretical and computational framework for studying fractional hydro-photo-thermoelastic wave propagation in poroelastic semiconductor media, incorporating the effects of microtemperature and nonlocal elasticity. The motivation for this study lies in addressing these gaps by integrating fractional-order heat conduction, microtemperature effects, and nonlocal elasticity into the governing equations of wave behavior. Fractional-order heat conduction and photo-thermoelastic and poroelastic dynamics provide a more precise representation of thermal transport and wave interactions in these complex systems. Using a two-dimensional (2D) fractional-order photo-thermoelasticity model, we derive the coupled governing equations for temperature distribution, carrier density, pore water pressure, displacement, and microtemperature. The normal-mode analysis technique is applied to solve these equations, incorporating nonlocal elasticity to account for nanoscale effects, yielding closed-form solutions for the field variables. The results are validated using numerical simulations, which are visualized graphically to elucidate the dynamic coupling of thermal, mechanical, and photothermal fields. Numerical simulations are performed using realistic material parameters for a porous semiconductor medium, enabling the visualization of wave dynamics under various conditions.
