Abstract
Surface Plasmon Resonance (SPR), an established optical sensing mode for providing quantified surface, is applied here to evaluate its suitability to provide optical parameters from metal layer measurements in a synthetic marine environment. We investigated silver noble metal films exposed to standard saline solution. Silver layers exhibit both long-term durability, and linear temporal reflectivity change, recorded in SPR minimum angle and SPR curve shape. Optical sensor design was achieved using Fresnel's optical theory for isotropic multi-layer media. We developed a datafitting routine, providing numerical real and imaginary permittivity, and thickness solutions for corroded surfaces.
