Magnetics, Dielectrics, and Wave Propagation with MATLAB® Codes

Future microwave, wireless communication systems, computer chip designs, and sensor systems will require miniature fabrication processes in the order of nanometers or less as well as the fusion of various material technologies to produce composites consisting of many different materials. This requires distinctly multidisciplinary collaborations, implying that specialized approaches will not be able to address future world markets in communication, computer, and electronic miniaturized products. Anticipating that many students lack specialized simultaneous training in magnetism and magnetics, as well as in other material technologies, Magnetics, Dielectrics, and Wave Propagation with MATLABR Codes avoids application-specific descriptions, opting for a general point of view of materials per se. Specifically, this book develops a general theory to show how a magnetic system of spins is coupled to acoustic motions, magnetoelectric systems, and superconductors. Phenomenological approaches are connected to atomic-scale formulations that reduce complex calculations to essential forms and address basic interactions at any scale of dimensionalities. With simple and clear coverage of everything from first principles to calculation tools, the book revisits fundamentals that govern magnetic, acoustic, superconducting, and magnetoelectric motions at the atomic and macroscopic scales, including superlattices. Constitutive equations in Maxwell’s equations are introduced via general free energy expressions which include magnetic parameters as well as acoustic, magnetoelectric, semiconductor, and superconducting parameters derived from first principles. More importantly, this book facilitates the derivation of these parameters, as the dimensionality of materials is reduced toward the microscopic scale, thus introducing new concepts. The deposition of ferrite films at the atomic scale complements the approach toward the understanding of the physics of miniaturized composites. Thus, a systematic formalism of deriving the permeability or the magnetoelectric coupling tensors from first principles, rather than from an ad hoc approach, bridges the gap between microscopic and macroscopic principles as applied to wave propagation and other applications.

About the Author :
Carmine Vittoria’s career spans 50–55 years in academia and goernment 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 ~500 publications in peer-reviewed journals, ~ 25 patents, and three other scientific books. Dr. Vittoria is also the author of a nonscientific books on soccer for children; memoirs: "Bitter Chicory to Sweet espresso", "Once Upon a Hill" and "Hidden in Plain Sight". and 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.
