N2 - Yttrium iron garnet (YIG) based frequency selective limiter (FSL) offers unique features of adaptive frequency selective filtering against intentional electromagnetic interference (IEMI). However, due to the nonlinear effect of spin waves, it is difficult to model YIG-based FSLs using commercial simulators. In this work, a recently developed circuit model is improved by adding in the conduction and dielectric losses, leading to more accurate prediction of the power limiting performance. An RLGC extraction method based on measured S-parameters is proposed to determine the distributed RLGC of a YIG-loaded transmission line Such a method eliminates the need for determining the material properties of YIG. Based on the extracted RLGC, the nonlinear insertion losses under different input power levels are predicted. They are in closer agreement with the measurement, proving the effectiveness of the proposed method. Furthermore, the model is utilized to predict effects of varied YIG-film dimensions and magnetic bias field. © 2022 IEEE.
