Extraction of effective parameters in terahertz time-domain spectroscopy

Formerly known as the gap in the electromagnetic spectrum, the terahertz technology is being developed in several fields of science. A terahertz time-domain spectroscopy system will be presented and used to obtain transmission spectra of organic samples. This work proposes the implementation of an algorithm able to extract effective optical parameters of the analyzed samples in terahertz and also their thickness, using only the transmittance as experimental data. Lactose samples were characterized using the proposed method.
