The present thesis is about the electrical properties of various materials in the earth’s upper crust. It is an attempt to better understanding regarding certain aspects of these properties which have undisputed importance and usefulness in the field of applied geophysics.Electrical properties of earth’s materials are important because techniques based on the propagation and scattering of electro-magnetic energies are widely used to investigate geological media in the earth’s science (Annan and Davis, 1976; Kozier and Strangway, 1975; Tayler et.al. 1974). The principle behind these techniques is that electromagnetic field generated by artificial and natural sources are scattered by variations in the electrical properties of the ground so that by studying the scattered fields on or above the earth’s surface, information about the sub surface geological structure may be obtained. The frequency dependence of electrical properties has been studied but geometric scattering properties of the samples have not been explored.
