Spectral properties of interacting magneto electric particles This paper describes mathematically most of the interactions of magnetically coupled nanoparticles in an a hot spot aggregation. This treatment includes the formation of contained vortex currents in an oscillating system and their anapole magnetic projections, energu transfer and confinement, the method of energy transfer between magnetic elements, and symmetry breaking qualities of the vortex systems. Abstract The linear magnetoelectric (ME) effect provides a special route for linking magnetic and electric properties. In microwaves, a local ME affect appears due to the dynamical symmetry breakings of magnetic-dipolar modes (MDMs) in a ferrite disk particle. The fact that for MDMs in a ferrite disk one has evident both classical and quantum-like attributes, puts special demands on the methods used for study of interacting ME particles. A proper model for coupled particles should be based on the spectral characteristics of MDM oscillations and an analysis of the overlap integrals for interacting eigen oscillating ME elements. In this paper, we present theoretical studies of spectral properties of literally coupled of MDM ME disks. We show that there exists the "exchange" mechanism of interaction between the particles, which is distinctive from the magnetostatic interaction between magnetic dipoles. The spectral method proposed in this paper may further the development of a theory of ME "molecules" and realization of local ME composites.
