Fano Resonance in an Asymmetric MIM Waveguide Structure and Its Application in a Refractive Index Nanosensor
Herein, the design for a tunable plasmonic refractive index nanosensor is presented.The sensor is Pop Up Tunnel composed of a metal⁻insulator⁻metal waveguide with a baffle and a circular split-ring resonator cavity.Analysis of transmission characteristics of the sensor structures was performed using the finite element method, and the in
