Sushil Misra is a Full Professor of Physics at Concordia University, Montreal, Canada. Professor Misra received his Ph.D. from Saint Louis University, USA, and spent sabbatical leaves at Harvard University, Paul Sabatier University (Toulouse, France), Technische Hogeshule (Delft, Holland), Monash University (Melbourne, Australia), and Cornell University. He has done extensive experimental and theoretical research in the area of electron paramagnetic resonance for the last 28 years, with some 210 papers to his credit. Currently, he is a collaborating faculty member at ACERT (Advanced Center for Electron Spin Research Technology at Cornell University). He has written numerous review articles and book chapters on EPR, and has been invited frequently as a specialist to present lectures at international conferences.

<b>F</b>illing the gap for a systematic, authoritative, and up-to-date review of cutting-edge techniques in EPR, this book covers both low and high frequency EPR, emphasizing the importance of adopting the multi-frequency approach to study paramagnetic systems in full detail by using the EPR method. In so doing, it discusses not only the underlying theory and applications, but also all recent advances - with a final section devoted to future perspectives.
