Our simulations indicate that perfect absorption efficiencies can be achieved for resonance wavelengths. The influence of core-shell microspheres geometry and lattice geometry is studied on absorption properties. For wavelength from 1.2 μm to 2.6 μm, an optimal combination of sphere and core radius was obtained to provide perfect absorption which can be wavelength adjusted. © 2013 AIP Publishing LLC.en0003-6951201321American Institute of PhysicsPhysikTechnikIngenieurwissenschaftenJournal Article10.1063/1.4832071Other
