Superconductivity and Electromagnetism

lt;p>Professor Teruo Matsushita has studied flux pinning and related electromagnetic phenomena in superconductors for 48 years. The first research field includes theoretical calculation of elementary pinning force of specific pinning centers and estimation of the pinning force density as a function of the elementary pinning force and number density. In the latter research field he establish the critical state theory that supports the well-known critical state model by using the first principles of minimizing the free energy in the reversible state followed by development to the irreversible state. The theoretical analyses of the longitudinal field problem and the effect of flux creep in high-temperature superconductors are also included in the latter category.  He is a member of The Institute of Electrical Engineers of Japan, The Japan Society of Applied Physics, Cryogenics and Superconductivity of Japan, and Institute of Physics (UK). In 2014 he published the Springer undergraduate textbook Electricity and Magnetism, which now boasts close to 2 million downloads.

"This book provides an extremely clear and comprehensive introduction to the topic of electromagnetic problems emerging in the case of superconductive materials. It covers not only basic fundamentals of the macroscopic theoretical description but also provides actual and interesting illustrations of modern applications of superconductivity."
