Research and development on plasma has expanded rapidly in recent years, covering a wide range of fields such as fusion energy development, plasma/ion propulsion, and semiconductor plasma processes. The lecture begins with the basic concepts and characteristics of plasma, and covers a wide range of topics about the behavior of charged particles and waves in plasma, low-temperature plasmas generated by electric discharge, the fluid description of high-temperature plasma, and the transport phenomena in plasma. We aim to efficiently learn important points of plasma physics and acquire knowledge useful for research and development using plasma.
By the end of this course, students will be able to:
1) explain basic concepts and characteristics of plasma,
2) explain basic equations governing plasma related phenomena,
3) apply ideas from plasma physics to practical plasma applications.

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
In the beginning of each class, solutions to exercise problems given in the previous class are reviewed. In the end of the class, students are given exercise problems related to the contents of the lecture. Students should check the course schedule and what topics will be covered beforehand, and it is strongly recommended for students to prepare and review those topics.
