2. Guided propagation in anisotropic media

The plane-wave model developed up to now showed that the anisotropy of a magnetic medium of the ferrite family is mainly coordinated by the polarizing static magnetic field.

It was also proved by solving the eigenvalue equation that the phenomena of radio wave propagation in the medium give rise to two wave numbers whose properties can be exploited to design non-reciprocal quadrupoles.

It also appeared that these phenomena reach their peak on the gyromagnetic resonance.

The propagation phenomena observed in ferrites also shared the common property of being stimulated by magnetic fields under circular or elliptical polarization.

The aim of this paragraph will be to transpose these mechanisms to the case of waves carried on guided structures generating quasi-TEM modes, or TE modes related to...
