Abstract

Possibility of magnetic energy accumulation inside silicon nanoparticles atthe conditions of resonant optical responses is investigated theoretically. Themagnetic field distributions inside silicon nanocylinders with and withoutcoaxial through holes are calculated using full-wave numerical approach. It isdemonstrated that such systems can be used for control and manipulation ofoptical magnetic fields providing their enhancement up to 26 times at thecondition of optical resonances. Obtained results can be used for realizationof nanoantennas and nanolasers, in which magnetic optical transitions playsignificant roles.
