Nanometer refractive index sensor based on water droplet cavity structure with rectangular short rod
In this paper, a novel nano sensor structure is proposed, which consists of a metal-insulator-metal waveguide (MIM) with rectangular icon track bar f250 baffles and a water droplet cavity with rectangular stubs (WDCRS).The WDCRS structure optimizes the sensitivity of a single water droplet cavity and makes the transmission curve clearer and smoothe
