sim-spr: an open-source surface plasmon resonance simulator for academic and industrial purposes

In this paper, an open-source simulation tool is proposed to evaluate the spr effect considering a multilayer structure. the open-source simulator is called sim-spr and it follows the principles of software engineering. furthermore, sim-spr is dedicated to analyze reflectance of prism-based spr sensors using otto’s configuration. it is important to emphasize that there is no available open-source simulation tool specifically built in this context in the literature. the sim-spr accuracy, efficiency, and reliability were analyzed by comparing our obtained results considering three different scenarios with two other simulation tools available in the literature, presenting minimal relative error. the results still include a sensitivity analysis of prism-based spr sensors focusing on resonant angle.
