Magnetics Dielectrics and Wave Propagation with MATLAB Codes

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 MATLABÂ 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 bookâs strength is in its step-by-step explanation of the procedure for unifying Maxwellâs 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. . Language: English
