OPTICAL ANTENNA-PROBES BASED ON METALLIC NANOSHELLS
Annotation
We investigate the possibility of using complex metallic nanostructures based on metallic nanoshells as near-field optical probes. Due to the effect of plasmon resonance such structures are able to effectively concentrate the energy of incident optical radiation to a subwavelength area. We present the results of numerical modeling of optical antennas electrodynamics performed by finite difference time-domain method. Also we investigate the ways of experimental fabrication of such nanostructures.
