General Description

A Y-type stripline ferrite circulator known from the paper “FDTD analysis of microwave circulators involving saturated magnetized ferrites” proposed by J. Lenge, A. Ahland, J. Kastner, and D. Schulz is considered.

Geometry

The dimensions of the ferrite circulator can be found in the reference paper.

The ferrite pills are 1 mm thick, their diameter is 5 mm and the parameters of the ferrite medium are as shown below.

The relative permittivity of the dielectric substrate is 9.4.
