Simultaneous Electric and Magnetic Two-Dimensional Tuning in Nonlinear Magnetic Transmission Line

This work proposes and demonstrates the concept of simultaneous electric and magnetic two-dimensional tuning (2D-tuning) in nonlinear magnetic transmission line (NLMTL). The proposed concept is briefly discussed through theory and experiments in different scenarios. First of all, one-dimensional tuning including electric and magnetic tuning is separately studied and the corresponding tuning capability is explored. Then, simultaneous electric and magnetic tuning is analyzed and validated to show that the corresponding tuning range is improved considerably. It is discovered that utilizing NLMTL enhances the tuning range five times compared to that of the electric tuning while 1.7 times to that of the magnetic tuning.
