Course description and aims

This lecture starts from the introduction of some basic quantities used for describing dielectric property of substances such electric field, electric displacement, polarization, dipole momentum etc. The polarization is the most important concept in the physics of dielectrics. Polarization mechanisms including frequency dispersion are explained in detail. For understanding electronic polarization, the concept of local field should be explained using classical Lorenz local field theory. The Clausius-Mossotti relation is explained for understanding microscopic electronic polarization and macroscopic dielectric constant. In the latter part in the lecture, frequency dispersion of polarization mechanism is explained, and applications of piezoelectric, pyroelectric and ferroelectric materials are introduced.

Student learning outcomes

The purpose of this lecture is to understand the basic concept and applications of ceramic dielectrics by learning some important physical constants to describe dielectric phenomenon. Furthermore, this lecture tri to educate students to think the applications of dielectric materials using knowledge of polarization mechanisms based on material science.
