Lecture
This lecture covers the high-frequency applications of RF devices up to 50 GHz, including the electromagnetic spectrum, soft magnets in RF, and the dynamic processes in soft magnets. It also discusses the application fields of soft magnets at different frequency ranges and the permeability variations as a function of frequency. The lecture delves into the behavior of materials with permittivity comparable to a single-domain uniaxial magnet, as well as the transmission and absorption regions in the spectral model of gyromagnetic interaction.
