Abstract

The existence of non-radiating sources with high reduction of far-field radiation and accumulation of electromagnetic field in the near-field zone is crucial for various branches of science from medical imaging to dark matter. Here a non-radiating electric source consisted of an ultra-high permittivity dielectric hollow disk excited by an electric point-like dipole antenna placed inside the disk is studied. We theoretically demonstrate that such a system supports anapole state with radiation suppression to the far-field. The radiation suppression is obtained by destructive interference between the point-like dipole antenna's radiation and the hollow disk's induced current.
