Numerical Optimization of a Divergence-Beam Surface Plasmon Resonance Sensor with CaF2/ZnO/Ag/ZnTe Multilayers for Alpha-Fetoprotein-Associated Refractive Index Sensing
This study presents a numerical investigation of a five-layer surface plasmon resonance (SPR) sensor employing a CaF2/ZnO/Ag/ZnTe configuration, optimized through the transfer matrix method at an excitation wavelength of 633 nm. The primary objective is to numerically maximize angular refractive index (RI) sensitivity...
