The proposed book is the first to report magnetic radiative structures inspired by metamaterial concepts. This book is unique since it combines the knowledge recently acquired by the authors in three different fields of research, metamaterial, magnetic materials, and nano-materials, toward the design of magnetic radiative structures. The book includes a detailed description of the analysis, design and implementation of full-space frequency and bias scanning leaky-wave antennas, low-profile monopoles, combined antenna-diplexer/duplexers, non-reciprocal radomes, novel electromagnetic boundaries for TEM waveguides or high efficiency planar antennas, selfbiased ferromagnetic nanowires, integrated millimeter-wave nanowire components with double ferromagnetic resonances.
