Quantized Lightwave Inducting Characteristics of a Nano‐Serrate Interdigitated Wiregrating Architecture Covered by an N‐Layered Graphene Coating

Abstract

ABSTRACT A nano‐serrate interdigitated wiregrating (NSIW) architecture covered with N‐layered graphene coating is proposed for quantifying induced incident light waves, and its transmission spectrum can be electrically tuned in the visible and near‐infrared (IR) regions. A quantitative optical resonance response mechanism is proposed based on the resonance arrangement of surface plasmon polaritons (SPPs) generated by the coupling of positive and negative net charges on the surface, as well as the localized surface plasmon polaritons (LSPs) of accumulated and attenuated net charges at the nanotip. The main model is based on quantized dipole‐type net charge resonance induction and directional transport, thereby achieving local accumulation and even nano‐focusing. The basic NSIW architecture can also be seen as a dipole‐type molecular antenna derived from traditional radio frequency electromagnetic systems, but exhibits its inherent quantized energy state in the discussed band. The experiment evaluated the evolution of transmission spectra of non‐polarized and polarized measurement configurations passing through the wavelength range of 0.2–5 µm. This study provides new insights into the nanoscale configuration of low‐dimensional graphene coatings based on quantified dipole resonance response.
