A refractive index (RI) based corrosion sensor that could measure the oxidation of iron metal to iron-oxide was numerically investigated with a finite element method. The sensor is based on an optical microring resonator with periodically arranged iron nanodisks (NDs) in a ring waveguide (WG). The m...
