“…In fact, much more efficient compact FDTD methods have been introduced recently, for instance: a compact FDTD method based on the alternating direction implicit (ADI) in which the time step is not limited by the CFL The simulations were performed on Pentium III computer using Matlab 7.1. criterion was presented in [20,21], a compact pseudo spectral time domain (PSTD) method in [22] and a compact FDTD method with weighted Laguerre polynomials in [23,24]. They have been applied to isotropic and anisotropic media; nevertheless, no application of these methods to anisotropic dispersive media characterized by a permittivity or permeability tensor with frequencydependent components (such as ferrites) has been reported, which make of this work the first to deal with this issue.…”

In this work, a compact finite-difference time-domain (FDTD) algorithm with a memory-reduced technique is proposed for the dispersion analysis of rectangular waveguides either fully or partially loaded with longitudinally-magnetized ferrite. In this algorithm, the divergence theorem is used to eliminate the longitudinal components of the electric and magnetic flux densities. The mobius transform (MT) technique is applied for the first time to obtain the equations relating the magnetic field to the magnetic flux density in a ferrite medium. Some examples are presented to validate the obtained algorithm with numerical results: good agreement is obtained with a significant reduction in the memory space requirement compared to the conventional algorithm.
