Nanostructured concentric gold ring resonator-based metasurface filter device

Abstract The paper reports on the filtering aspect of concentric gold ring tubular resonator-based metasurface – the periodic structure is considered as plasmonic metamaterial in the present investigation. The proposed filter is designed and modeled based on the variation of the incident angle of the electromagnetic (EM) waves in the frequency range of 200–900 nm under the transverse electric (TE) polarization of the incident field. The nanostructure is engineered in a pool of unit cells over a dielectric medium, and each unit cell is comprised of concentric gold tubular rings with continuous upward increment in their radii; the separation between rings remains as free-space. The effective EM parameters, obtained from the simulation of the S-parameters, indicate that the metamaterial structure exhibits transmission bands, which can be shifted by altering the magnetic bias. The device exhibits over 95% transmission of the incident field. The results reveal possible applications of the proposed metasurface-based structure as optical filter.
