“…A modified approach to incorporate Polder-model ferrites in FDTD based on equivalent resistor-capacitor-inductor circuit models is formulated in [215]. An analysis of the numerical errors due to losses in the FDTD modeling of ferrites is presented in [216]. The inclusion of PML absorbing boundary conditions in a FDTD algorithm for the modeling of saturated ferrites was recently considered in [201].…”

“…Within the several frequency-dependent anisotropic dispersive materials, the magnetised ferrite has been extensively employed in the manufacturing of microwave devices and so on [6][7][8]. To simulate its unique non-reciprocity property, the SO-FDTD and the ADE-FDTD approaches are carried out in the anisotropic magnetised ferrite [5,9,10].…”

In order to efficiently simulate the symmetrical structures in the cylindrical coordinate system, the implementation of the complex frequency‐shifted perfectly matched layer based on the body of revolution finite‐difference time‐domain algorithm is proposed for analysing the magnetised ferrite microwave structures. To improve the computational efficiency in the magnetised ferrite domain compared with the existing calculation methods, the bilinear Z‐transform for the simulation of the dispersion relationship of the magnetised ferrite is proposed. The proposed implementations can not only improve the computational efficiency but also obtain a considerable absorbing performance. Numerical examples based on the magnetised ferrite microwave structures are carried out to demonstrate the effectiveness and efficiency of the proposed formulations.
