Simulation on the properties of localized surface plasmon resonance(LSPR) of different sized hexagonal Ag nanoarrays embedded in the amorphous oxidized silicon nitride(a-SiN_x:O) matrix has been carried out by using COMSOL Multiphysics and FDTD Solution simulation software.Through the calculation of the scattering and absorption cross section of Ag array with different radius,we find that the position of extinction peaks red-shift from 460 to 630 nm when the radius of nanoparticles of hexagonal Ag arrays in...
