Thz absorption
WebbIn physics, terahertz time-domain spectroscopy(THz-TDS) is a spectroscopictechnique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitudeand the phaseof the terahertz radiation. Fourier transform of the above pulse. Webb4 nov. 2015 · THz time-domain spectroscopy (THz-TDS) has proven to be a particularly well-suited technique to investigate the morphology of many non-polar materials [1, 2].By exploiting absolute values of distinct absorption lines, it is possible to distinguish between different crystalline forms of a given material, to observe polymorphism, and to …
