Paper Abstract

The nanoshell optimization for obtaining large electromagnetic absorption efficiency is studied, and the structure with photo-thermal polarity is studied. It is found that the resonance wavelength is determined mainly by diameter ratio of core /shell, the energy absorption peak shifts to shorter wavelength by increasing the shell thickness. And as the particle size increases, absorption peak increases significantly first and then decays. The electromagnetic losses for single particle and for 3×3 planar arrangement are analyzed. The individual nanoshell in the arrangement shows unique distribution with polarity.
