Topological properties of microwave magnetoelectric fields.

It is shown that magnetoelectric fields originated from MDM ferrite disks can be distinguished by topological portraits of the helicity parameters and can have a torsion degree of freedom.

It is demonstrated that the unique topological properties of the fields in a ferrite disk are intimately related to the symmetry breaking effects of magnetostatic oscillations, which allow one to propose new-type subwavelength microwave structures.

Magnetic-dipolar and electromagnetic vortices in quasi-2D ferrite discs

Evidence for eigen-MS power-flow-density vortices in a ferrite disc is given and it becomes evident that the reason for stability of the vortex configurations in saturated ferrite samples is completely different from the nature of stability in magnetically soft cylindrical dots.
