Course description and aims

This course focuses on the basic characteristics of dielectric and magnetic with macroscopic and microscopic theories in dielectric and magnetic materials. The course enables students to understand phenomenon of polarization and magnetization and their related materials and application.
Dielectric and magnetic materials are used in many cases in present electric and electronic engineering, for example, dielectric materials are used as not only insulators for power cable but also gate insulator in MOSFET, magnetic materials are used as not only magnet core in transformer and coil but also magnetic recording.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand basic characteristics of dielectric and magnetic materials for electric and electronic engineering.
2) Understand nature of polarization and explain dielectric dispersion, complex dielectric constant, electric conduction mechanism in dielectric and insulator materials, and ferroelectricity.
3) Understand nature of magnetism and explain magnetization, magnetic moment, spin, diamagnetism, paramagnetism, and ferromagnetism.

Keywords

dielectric materials, dielectric polarization, dielectric constant of gas and solid, frequency characteristics of dielectric polarization and complex dielectric constant, ferroelectricity and phase transition, magnetic materials, magnetization and magnetic moment, spin, diamagnetism, paramagnetism, and ferromagnetism

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
