Abstract: The dielectric properties of any material is the most important parameters to judge its microwave absorptive properties. This paper reviews the sufficient conditions for absorption of electromagnetic waves by a material by taking electric permittivity and magnetic permeability of materials into consideration. At the end of this paper the electric permittivity and magnetic permeability of different materials having single layer (composite structures) and multilayer structure is compared to see the effect of electric permittivity and magnetic permeability.
