Microwave and millimeter-wave characterization of axially magnetized semiconductor disk

Magnetized ferrite resonators have so far been used to produce tunable microwave filters and junction circulators up to around 40 GHz. Above this frequency range, the nonreciprocal behavior of commercial ferrite decreases with increasing losses, whereas the losses in magnetized semiconductors become more acceptable. In this article, the gyrotropic characteristics of magnetized semiconductor disk resonators are investigated using applied field/frequency parameters. The nonlinear relationship between the existing tensor entry description and the field/frequency solution is established. The sensitivity of the resonant frequency to geometrical and material properties of the semiconductor disk is observed and tabulated. Finally, the S-parameters of a magnetized two-port semiconductor network are derived at microwave and millimeter-wave frequencies. The aim of this work is to provide simulated results for calibrating the semiconductor resonator, essential for conducting successful experiments on semiconductor junction devices.
