Plasma is electrically neutral ionized gas consisting of electrons and ions. Plasma plays an important role in modern engineering. Theory and concepts dealing with the plasma are fairly common in the electrical and electronic engineering.
In this course, students will learn from the basics of plasma physics, plasma generation, measurement, to industrial applications of plasma.
It includes excitation and ionization, motion of charged particles in electromagnetic fields, plasma as particles, plasma as fluid, collision and transportation, confinement of plasma, wave in the plasma, and plasma measurement.
[Goal] The concept and discussion of plasma physics have become one of the fundamentals in all aspects of science and engineering. In particular, electrical and electronic engineers and researchers must learn plasma physics as well as electromagnetism. The goal is to understand fundamentals and applications of plasmas from the viewpoints of engineering, starting from movement of charged particles in electromagnetic field, characteristics as a group of charged particles, and ionization phenomena.
Plasma, discharge, ionization, excitation, Bltzmann equation, drift motion, magnetic moment, dispersion relation, sheath, thermonuclear fusion
