State-of-the-Art Review on Characterization of Porous Media Using Wave Propagation

A number of studies have been made by using the concept of porous media in the areas of applied science and engineering mechanic (viz., acoustics, geomechanics, soil mechanics, rock mechanics), engineering (viz., petroleum engineering. bio-remediation, construction engineering), Geosciences (viz., hydrogeology, petroleum geology, geophysics) and material science. In this context, researchers have also characterized soilmass, which happens to a porous media using various methods. Moreover, many empirical correlations have been developed for the determination of various soil parameters. However, the use of wave propagation methods for the characterization of porous media like soils is comparatively a new area and has been a subject of interest among various researchers since last few decades. This paper gives a state-of-the-art review on characterization of porous media using the wave propagation technique with the theories and formulae given by various researchers. It is strongly believed that the present state-of-the-art review will give a clear understanding on wave propagation in porous media and will serve as a basic platform for various future studies which have not been given proper attention before.
