(а) Experimental sample of the nontrivial nonradiating all-dielectric anapole based on four- SrTiO3 cylinders with diameter 5 mm, excited by electric dipole antenna in the center of meta-molecule. (b) The experimental spectra S21 of power received at second antenna relative to the power input to the source: without and with metallic plate on the top of the source, where the black curve corresponds to the case without metallic plate and the red curve is for covered open end of the source by metal plate.
