This article aims to highlight recent activities in THz group at QMUL. These include progress in data processing techniques related to material parameter extraction procedures, characterization of water-based highly absorbing solutions, programming techniques used to facilitate data acquisition and investigations in the field of new coherent THz sources. The implementation and development of quasi-optic THz components is also described here. One of the group’s aims is to establish metrological measures allowing comparison of results obtained using THz-TDS by various groups worldwide.References
