ABSTRAKT

In the present problem the reflection of plane harmonic waves at the permeable (or impermeable) boundary of dissipative porous solid is investigated. Porous medium is dissipative in nature due to the viscosity of pores fluid. As a result of incident wave at the stress-free surface, it is found that three reflected waves exist in a dissipative porous solid. All the reflected waves are inhomogeneous in nature (i.e., dissimilar direction of propagation and attenuation). The segmentation of incident energy among versatile reflected waves at the stress-free surface is computed at both permeable and impermeable boundaries. Due to the dissipative nature of medium, conservation of net energy flux at the stress-free surface is prevailed in the mien of an interaction energy between two dissimilar waves. The essences of porosity, Poisson's ratio, viscoelasticity, pore characteristics, and wave frequency on various energy shares are depicted graphically and discussed.
