Accuracy Enhancement in Refractive Index Sensing via Full-Spectrum Machine Learning Modeling

We present a full-spectrum machine learning framework for refractive index sensing using simulated absorption spectra from meta-grating structures composed of titanium or silicon nanorods under TE and TM polarizations. Linear regression was applied to 80 principal components extracted from each spec...
