Because future microwave, magnetic resonance, and wave propagation systems will involve miniature devices, nanosize structures, multifunctional applications, and composites of various types of materials, their development requires distinctly multidisciplinary collaborations. That means specialized approaches will not be sufficient to satisfy requirements. Anticipating that many students lack... Read more

Biography

Carmine Vittorias career spans 40–45 years in academia and research establishments. His approach to scientific endeavors has been to search for the common denominator or thread that links the various sciences to make some logical sense. The fields of study include physics, electrical engineering, ceramics, metallurgy, surface or interfaces, nano-composite films. His interest in science ranges from the physics of particle–particle interaction at the atomic scale to nondestructive evaluation of bridge structures, from EPR of a blood cell to electronic damage in the presence of gamma rays, from design of computer chips to radar systems, from microscopic interfacial structures to thin film composites. The diversity and seriousness of his work and his commitment to science are evident in the ~ 400 publications in peer-reviewed journals, patents, and two other scientific books. Dr. Vittoria is also the author of a nonscientific book on soccer for children. He is a life fellow of the IEEE (1990) and an APS fellow (1985). He has received research awards and special patent awards from government research laboratories.

Dr. Vittoria was appointed to a professorship position in 1985 in the Electrical Engineering Department at Northeastern University, and was awarded the distinguished professorship position in 2001 and a research award in 2007 by the College of Engineering. In addition, he was cited for an outstanding teacher award by the special need students at Northeastern University. His teaching assignments included electromagnetics, antenna theory, microwave networks, wave propagation in magneto-dielectrics, magnetism and superconductivity, electronic materials, microelectronic circuit designs, circuit theory, electrical motors, and semiconductor devices.

... Even if you thought you understood magnetism, it is likely that you would learn a lot ... Many books on magnetism end where Vittoria’s is just beginning. ... An unusual feature of Vittoria’s book are the solutions that are included to the problems at the end of each chapter. These solutions form a lengthy set of examples for sorting out the many theories and models now used in trying to understand magnetism. ... If you make magnetism your profession, or are just casually involved with magnetic materials, it is worth reading a book such as Vittoria’s. ... about as approachable as this subject can get.
