Retrieving material and metamaterial parameters directly from time-domain spectroscopy time trace

Abstract: We present the Fit@TDS software that enables the retrieving of the refractive index from a time-domain spectroscopy experiment. The software does not only use common methods of frequency-domain refractive index retrieving but also include a time-domain optimization algorithm that enables fitting directly the material parameters using of the Drude-Lorentz model or meta materials through the time-domain couple mode theory.
