Photothermal Response for the Thermoelastic Bending Effect Considering Dissipating Effects by Means of Fractional Dual-Phase-Lag Theory

We analyze an extension of the dual-phase lag model thermal diffusion theory to accurately predict contribution thermoelastic bending (TE) Photoacoustic (PA) signal in a transmission configuration. To achieve this, we adopt particular case Jeffrey’s equation, Generalized Cattaneo Equations (GCEs). Obtaining temperature distribution by incorporating effects fractional differential operators enables us determine TE solid samples accurately. This study contributes understanding mechanisms that contribute PA and highlights importance considering analysis bending. As result, can signal’s component. Our findings demonstrate lead wide range behaviors, including dissipative related anomalous diffusion.
