  • Abstract
    A three-dimensional FDTD approach for the analysis of microwave circulators is presented. The underlying theoretical fundamentals are introduced, including a model for saturated magnetized ferrite material. The detrimental effect of demagnetizing fields is examined and evaluated for several examples. The simulated scattering characteristics are compared with experimental results.
