Analysis and optimization of the two-channel SPR interferometer sensor design

Modeling calculations were carried out on the surface plasmon resonance interferometry (SPRI) technique the experimental studies of which were previously described. This effort was carried out with the goal to clarify the dependencies of the sensing function on the many parameters and variables that impact the performance of this technique. In particular, the calculations focused on the comparison of the sensing function between SPR with interferometry and SPR-only at fixed angles. MATLAB was used in these calculations because it provided detailed control of the modeling efforts.
