Nanoscale Temperature Sensor with Dual Circular and Square Structures Based on MIM Waveguides

Nanoscale Temperature Sensor with Dual Circular and Square Structures Based on MIM Waveguides

This paper proposes a refractive index sensor with high sensitivity, which operates based on the Fano resonance phenomenon. The sensor is constructed using a metal–insulator–metal (MIM) waveguide integrated with a double square ring (DSR) configuration, enabling enhanced performance in refractive in...
