Abstract

Dielectric losses, that characterize the transformation of electrical energy into heat energy, are an important electro-physical parameter of the dielectrics. In fact these losses are determined by the material’s effective conductivity, so it is one of the most practical characteristics. Therefore, this article describes the main loss mechanisms and their contribution to the microwave effective conductivity of the dielectric materials. The frequency dependence of the effective conductivity is analyzed.
