Abstract

This study describes a sensitivity analysis of absorption spectra for NIR-SWIR absorbing dyes relative to the inverse analysis of measured spectra. Absorption spectra of NIR/SWIR-absorbing dyes obtained by inverse spectral analysis provide information for estimating the dielectric response functions. Sufficient sensitivity of absorption spectra relative to inverse spectral analysis implies that estimated dielectric response functions can be used for the construction of approximate effective medium models capable of estimating reflectance from dye formulations on substrates, e.g., fabrics. The results of this study provide the foundational concepts for ensembles of absorption functions, which support the modeling and prediction of dielectric responses.
