Definition
Dielectric properties. Those characteristics of poorly conducting materials that determine their interaction with electric fields.
Introduction
Dielectrics are a class of materials that are poor conductors of electricity, in contrast to materials such as metals that are generally good electrical conductors. Many materials, including living organisms and most agricultural products, conduct electric currents to some degree, but are still classified as dielectrics. The electrical nature of these materials can be described by their dielectric properties, which influence the distribution of electromagnetic fields and currents in the region occupied by the materials, and which determine the behavior of the materials in electric fields. Thus, the dielectric properties determine how rapidly a material will warm up in radio frequency or microwave dielectric heating applications. Their influence on electric fields also provides a means for sensing...
