Wave behavior at the interface of inviscid fluid and NL bio-thermoelastic diffusive media

This work throws light on the reflection and transmission phenomenon due to incident plane longitudinal wave at a plane interface between inviscid fluid half-space and a nonlocal bio-thennoelastic diffusive half-space. The governing equations are formulated by adopting nonlocal heat conduction and mass diffusion along with dual phase lag (DPL) model. The amplitude ratios are obtained analytically and these amplitude ratios are used to drive energy ratios. The distribution of energy of incident wave among reflected and transmitted waves are obtained. The obtained ratios are impacted by angle of incidence, frequency and different properties of media involved. Numerically examined energy ratios are displayed in the form of graphs to know the effect of nonlocal parameters, lagging times, stiffness and blood perfusion rate.
