Anapole arising from a Mie scatterer with dipole excitation
We examine theoretically that an electric dipole close to a subwavelength sphere can yield an anapole (the dipole-sphere system is a nonradiating source). Physically, the anapole arises when the dipole induced by the source inside the sphere cancels out with the dipole contribution of the source wit...
