Course overview and goals
There are currently many devices using dielectricity that have been put into practice, and dielectricity has become an important area of material science. Polarization controls dielectricity. Students in this course will first gain a classical understanding of the concept of polarization through explanations from the perspective of the electromagnetism of dielectricity, followed by the instructor using classical physics and quantum theory to explain the inducement mechanisms of polarization. The polarization of a material varies with its frequency. This phenomenon is called dielectric dispersion, and is important for understanding dielectrics from a material science perspective, and applying dielectrics. The first half of this course deals with paraelectrics which are polarized by an electric field, but the latter half covers theories and applications of piezoelectric materials which are polarized by stress, pyroelectrics which hold spontaneous polarization without an external signal, as well as ferroelectrics, for which the orientation of spontaneous polarization changes with the electric field.
Course description and aims
The purpose of this lecture is to understand the meaning of physical quantities to describe dielectric property of substances as well as the concept of polarization based on the material science. Furthermore, this lecture aims to recall electromagnetic theory, thermodynamics, quantum physics etc., through the learning of dielectricity.

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
None required.
Reference books, course materials, etc.
Course materials are provided during class.
Evaluation methods and criteria
1) Students will be assessed on their understanding of "theory of polarization", "dielectric relaxation", "ferroelectricity", "piezoelectric materials and their application".
2) Students' course scores are based on midterm and final exams (80%) and exercise problem in every class(20%).
