Course description and aims

 The course is to achieve good comprehension of fundamentals of plasma physics with the elements of mechanics, electromagnetism, thermodynamics, and statistical mechanics, and so on taken in undergraduate curriculum. In the course, the issues on single charged particle and collective plasma-fluid motions in electromagnetic field are given in the former half, and the latter is devoted to generation of waves in plasma.
 The physics of plasma has been growing up to be an important issue in the studies of fusion plasma, plasma-processing relevant to semiconductor manufacturing, in addition to those of the auroral ionosphere and space plasma, being indispensable for interpretation of complex physical phenomena in the fields. The course of plasma physics is for beginners and helps them gain improved comprehension of the complex-system sciences mentioned above.
