Retraction: Effect of localized surface plasmon and surface plasmon polariton modes on properties of metamaterials

Abstract

We present the effects of localized surface plasmon (LSP) and surface plasmon polariton (SPP) modes on transmission peaks and resonance frequency of a compound structure metamaterial consisting of periodic metallic particle and hole arrays. During simulation, the lateral interval (Lx) between the metal particle and hole arrays is increased but the longitudinal interval (L) remains unchanged. Simulated results indicate that the main transmittance peak is enhanced and the resonant frequency red-shifted when Lx is increased, while the high-frequency transmittance peak is reduced and its resonance frequency is unchanged. We find that the increase in the intensity of SPP modes leads to the variation of the main transmittance peak, and the increase of the intensity of LSP modes results in the reduction of the high-frequency transmittance peak with increasing Lx.
