High Sensitivity Plasmonic Sensor Based on Fano Resonance with Inverted U-Shaped Resonator
Herein, we propose a tunable plasmonic sensor with Fano resonators in an inverted U-shaped resonator. By manipulating the sharp asymmetric Fano resonance peaks, a high-sensitivity refractive index sensor can be realized. Using the multimode interference coupled-mode theory and the finite element met...
