FIG. 4. (Color online) The power-flow density distributions in a near-field vacuum region (75 μm above a ferrite disk) for the 2 resonance
(f = 8.652 GHz). (a) A general picture in a waveguide, (b) a detailed picture near the region of a ferrite disk. One has strong localization and
strong reflection of electromagnetic fields in a waveguide.

space. Reflecting the nature of coupled modes of optical fields
and material excitations, the physical quantities associated
with optical near-field interactions have distinctive properties
in comparison to optical radiation in the far field [27]. These
effects in optics can be useful for understanding the physics of
the MDM-vortex polaritons in microwaves.

For a more detailed analysis of the field polarization in
MDM-vortex polaritons, we insert a piece of metal wire inside
a waveguide-vacuum region. A metal rod is made of a perfect
electric conductor and has a very small size compared to
the free-space electromagnetic wavelength: the diameter of
200 μm and the length of 1 mm. When such a small rod
