Time-domain spectroscopy allows fast and broadband measurement of
the optical constants of materials in the terahertz domain. We
present a method that improves the determination of the optical
constants through simultaneous determination of the sample
thickness. This method could be applied to any material with
moderate absorption and requires only two measurements of the temporal
profile of the terahertz pulses: a reference one without the sample
and one transmitted through the sample.
