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 specialized training in magnetism and magnetics, Magnetics, Dielectrics, and Wave Propagation with MATLAB® Codes avoids application-specific descriptions.Instead, it connects phenomenological approaches with comprehensive microscopic formulations to provide a new and sufficiently broad physical perspective on modern trends in microwave technology. Reducing complex calculation approaches to their simplest form, this book’s strength is in its step-by-step explanation of the procedure for unifying Maxwell’s equations with the free energy via the equation of motion. With clear and simple coverage of everything from first principles to calculation tools, it revisits the fundamentals that govern the phenomenon of magnetic resonance and wave propagation in magneto-dielectric materials.

Introduces constitutive equations via the free energy, paving the way to consider wave propagation in any media

This text helps students develop an essential understanding of the origin of magnetic parameters from first principles, as well as how these parameters are to be included in the large-scale free energy. More importantly, it facilitates successful calculation of said parameters, which is required as the dimensionality of materials is reduced toward the microscopic scale. The author presents a systematic way of deriving the permeability tensor of the most practical magnetic materials, cubic and hexagonal crystal structures. Using this simple and very general approach, he effectively bridges the gap between microscopic and macroscopic principles as applied to wave propagation.

Über Autor(innen)

Carmine Vittoria’s 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.
