Numerical simulation of some planar microwave gyrotropic structures

The numerical simulation of different gyrotropic structures plays an increasing role in modern microwave practice. In comparison with the usual analytical/experimental methods known for a number of years, a considerable saving of time and effort combined with some new possibilities for improvement of the analysis before realization of the structures are possible. This new alternative is demonstrated for the case of stripline circulators operating in S-band and below ferromagnetic resonance. The consideration is done with a planar model analysis which offers a reasonable compromise between time consumption and accuracy
