A metal-insulator-metal waveguide-based plasmonic refractive index sensor for the detection of nanoplastics in water

Abstract A metal-insulator-metal waveguide-based square-ring resonator plasmonic refractive index sensor is designed and optimized for achieving high sensitivity. The sensitivity of the sensor critically depends on the physical dimension and the geometrical parameters of the resonator. Systematic st...
