Induced torsion effects in microwave structures with magnetoelectric fields

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

At ferromagnetic-resonance frequencies, in small ferrite samples so-called magnetic-dipolar-mode oscillations can be excited. The near fields in vacuum, originated from a ferrite disk with these oscillations, are unidirectional rotating fields. When a thin metal wire is placed above such disk, unique torsion electric currents are induced. We analyze analytically these torsion effects. The torsion currents create the fields with unique topology. The shown results could be useful for development of microwave microscopy of chiral biological structures.
