Plasmonic anapole metamaterial for refractive index sensing [PDF]

open access: yesPhotoniX, 2022
AbstractElectromagnetic anapole mode is a nonradiative state of light originating from the deconstructive interference of radiation of the oscillating electric and toroidal dipole moments. The high quality anapole-related resonances can be used in enhancing nonlinear electromagnetic properties of materials and in sensor applications.
