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.
