intriguing standing wave numbers and plasmonic effects on the solid-metal/metal-shell nanorod surface

In this paper, the intriguing standing wave numbers (swns) and surface plasmon resonance (spr) effects on the solid-ag/ag-shell nanorod surface are numerically investigated by using finite element method. various spr effects due to the variation in rod aspect ratio (ar) and shell thickness on the scattering cross section (scs), electromagnetic (em) wave patterns, and the swns on the solid-ag/ag-shell nanorod surface are discussed in detail. results reveal characteristic features of plasmon modes with respect to swns in photoluminescence images, which can enable us to obtain the mechanism of em wave distributions near the solid-ag/ag-shell nanorods. the large em wave with respect to their swns on the metal nanorod surface is very important for the applications of metal nanorod to be used to design devices like wavelength-selective photodetector, modulators, waveguides, metal nanorod-based solar cells, and plasmonic nanoantenna.
