In this book the analysis and design of induction heating of poor electrical conduction materials are studied. In the first chapter, the mathematical tools for coupled electromagnetic and thermal phenomena are introduced. In the second chapter, these tools are used to analyze a radio frequency inductive plasma installation. The third chapter describes the methodology of designing a low frequency plasma transformer. The fourth chapter studies the feasibility of the thermo inductive technique for non destructive testing and the lost chapter is dedicated to the use of induction heating in the life cycle of carbon reinforced composite materials.
