Abstract

In optics the field chirality on the subwavelength scales can be obtained based on special form plasmonic structures Recently it was shown that with use of quasi 2D ferrite disks with magnetic dipolar mode MDM oscillations one can observe near field chirality in microwaves The MDMs are energy eigenstate quantized oscillations The near field in vacuum originated from a MDM ferrite disk called magnetoelectric ME fields carry both spin and orbital angular momentums They are characterized by power flow vortices and non zero helicity Because of chiral topology of ME fields in a near field region far field chirality and orbital angular momenta can be observed In this lecture we consider ME field chirality in the near and far field regions of microwave radiation We focus both on physics and application of this effect
