Absorption avoided resonance crossing of hybridization of silicon nanoparticles and gold nanoantennas

Abstract The near-field coupling between a high-refractive-index nanoparticle and gold nanoantennas is investigated theoretically. The absorption enhancement and also avoided resonance crossing in the absorption cross section spectra were observed with the hybridization system due to the coupling be...
