Abstract: We describe a novel plasmonic-mode engineering, enabled by the structural symmetry of a plasmonic crystal with a metallic oligomer as unit cell. We show how the oligomer symmetry can tailor the scattering directions to spatially… read more here.

Abstract: An all-dielectric periodic array is proposed to form plasmon lattice resonances (PLR). In the array, Si nanopillars are on top of SiO2 nanopillars, and SiO2 nanopillars are on top of quartz substrates. The simulated results… read more here.

Abstract: The figure of merit (FOM) of plasmon lattice resonance (PLR) sensors based on the array of metal/Si/SiO2 nanoparticles has been investigated. We demonstrate the shape and material of metal nanoparticles have remarkable effects on the… read more here.
