“…Using of LC - resonance in structures containing the spherical metallic inductance elements was considered in refs 14 , 15 and golden rectangular micro-rod 16 . To the contrary, the examples of inductance excited by displacement currents in non-metallic elements and providing the formation of resonant frequencies were calculated for all-dielectric cylinders 17 and rings 18 . Using of displacement currents in dielectric structures opens the possibility to combine the inductive and capacitive properties in one element.…”

The theoretical basis and experimental verification of resonant phenomena in the electromagnetic fields generated by displacement current in the near zone of dielectric ring is presented. According to the traditional viewpoint, the dielectric has an influence on the electric field inside resonator. To the contrary, we demonstrate that the dielectric ring exhibits magnetic properties at resonance. The sliding incidence of plane microwave on this weakly absorbing ring is shown to provide the sharp and deep resonance in the components of generated field; this low loss circuit is operating as a resonant dielectric magnetic dipole. Splitting and broadening of resonance in the pair of these dipoles dependent upon their mutual arrangement is recorded. The phase shift equal to π between the magnetic components of incident and generated wave indicating the formation of negative magnetic response is demonstrated. Perspectives of using of this simple sub wavelength resonant magnetic dipoles in the all-dielectric circuitry are discussed.

We review various forms of dielectric ring-shaped oscillating circuits excited by displacement currents due to the grazing incidence of GHz microwaves. Such circuits with azimuth displacement currents form resonant dielectric magnetic dipoles. We calculate and measure resonances in field spectra in the near zone of such dipoles. We demonstrate the inversion of the magnetic inductance flux and the formation of a negative magnetic permeability in the resonant range of dielectric magnetic dipoles. We also investigate, both analytically and experimentally, the resonant interaction spectra of a pair of magnetic dipoles excited by displacement currents. Finally, prospects for using these dipoles to model all-dielectric nanostructures with alternating-sign magnetic permeability are discussed.
