This book describes wave propagation in magneto-dielectric materials. The text considers the magnetic state of a magnetic ion, for example, at the atomic scale, and provides a mathematical link to wave propagation at the macroscopic scale. It presents qualitative and quantitative arguments to calculate magnetic parameters from first principles. This book's theoretical approach combines macroscopic free magnetic energy with Maxwell's equations to yield wave propagation characteristics of magneto-dielectric materials. The author provides a clear understanding of the origin of magnetic parameters and how to calculate these parameters as the dimensionality of materials is reduced toward the microscopic scale.
