What are dielectrics?
I found this little snippet of information: Dielectrics is a field of knowledge that belongs not only to physics and chemistry, but also to electrical engineering. Dielectrics is not confined to the narrow area of “insulators”, but to any non-metal when their interaction with electric or electromagnetic fields is of interest. Polarisation and the dynamics of electric charges are at the heart of dielectrics. These are often described in terms of macroscopic properties such as permittivity, dielectric loss and breakdown strength. Electrical engineers have characterised dielectrics macroscopically using field vectors, equivalent circuits and reliability statistics. In contrast, the physicist and chemist have pushed forward the understanding of dielectric response in terms of molecular and structural response and relaxation. Many of the fundamental problems have now been addressed and it is now possible to move from “dielectric analysis” to “dielectric synthesis”. This is of considerable i
