Abstract

Tuning electric and magnetic response of dielectric structures at the nanoscale is a very important task nowadays. Multipole decomposition is a useful instrument to analyze and then control an opical response. Here we show the way to excite magnetic octupole moment by nanostructuring dielectric scatterer in near-IR spectral range. This response leads to magnetic hot-spots generations and a eresonant peak in scattering cross-section. Our results can be widely used to design novel metasurfaces avoiding diffraction limit, for particle trapping and imaging applications.
