Analysis of RF Generation Process in a Bench Compact Gyromagnetic Line

Gyromagnetic coaxial lines are considered nonlinear transmission lines due to the nonlinear effects of the domain magnets of the ferrites loaded in their coaxial inner conductor, and their main applications are in defense as a high-power microwave (HPM) device used in mobile platforms for shutting down drones or disrupting enemy communications on the battlefield. At INPE, a developed compact bench gyromagnetic line resonated at 1.9 GHz with lack of frequency tunability by both axial and azimuthal magnetic fields. The paper’s goal is to understand all the physics behind the process of RF in this experiment, where we present a consistent description of the phenomenon based on the analysis of the magnetic torque equation to obtain the susceptibility tensor for the AC ferrite magnetization.
