ABSTRACT
A class of composite dielectric materials refers to a two-phase refer ، host inclusion system in which the inclusion is a discrete- phase of conducting medium ( such as metals ، semiconductors ، or solid electrolytes ) dispersed randomly or textured as an orderly embedment in the host medium which forms a dielectric receptacle . such composite are essentially dielectric – conductor mixtures and have Unique ( effective ) dielectric properties due to the fact that the constituent phases have extremely opposite characteristics as regards their electrical susceptance and the associated conduction phenomena .
