THz Time Domain Test Bench

The THz TDS system, based on a NPL design,  has been adapted to accommodate fluid and gaseous-based systems for study, by either reflection or transmission configurations. The current value of our Terahertz Laboratory facility is about £700k.

Besides routine applications of the facility for general magneto-optic characterisation of solid-state dielectric and photonic materials, capability has been developed for experimental support of GROMACS (molecular dynamics modelling) studies of dissolved bio-molecular systems. The historical aim of the Antenna Group has been metrology and so methods are continually being developed and perfected to have TDS performed with a comprehensive handling of errors, particularly for characterisation of fluid samples.

Particular applications include:

• Selective activation of chemical bonds by active coherent THz spectrometry
• Coherent THz Spectroscopy for the Rapid Detection and Characterization of Bacterial Spores
• Terahertz signature of diseased cartilage
• Exploring protein structure and dynamics using Terahertz spectrometry
