Modeling and parameter retrieving in time domain spectroscopy of material and metamaterial

Résumé

Abstract In this proceeding, we present a software Fit@TDS that enables to retrieve the refractive index of a sample from a timedomain spectroscopy experiment. The software include commonly used methods where the refractive index is extracted from frequency domain data. This method has limitations when the signal is too noisy or when the absorption peak saturates the absorption. Thus, the software includes as well a new method where the refractive index are directly fitted using a model (the Drude-Lorentz for example) in the time domain. This method uses an optimization algorithm that retrieves the parameters of the model corresponding to the studied material. In this proceeding, we explain the methods and test them on fictitious samples to probe the feasibility and reliability of the proposed model.
