THz time-domain spectrometry (TDS) probes the complex polarization response of materials. Various analytical procedures are applied by many to extract the associated material optical constants. This has commonly been done by iteratively varying material parameters in order to achieve a match between experiment and a theoretical transfer function (TF). The… (More)
In preliminary work, a millimeter-wave vector network analyzer is used to analyze pectate lyase and a sequenced concentration of glucose solutions. Data reveal concentration-dependant spectra for glucose and Ca<sup>2+</sup>-sensitive spectra for pectate lyase.
This paper 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… (More)
A device for quantifying glucose and cytosine HCL by THz-TDS is described. Absorption spectral data showed concentration-dependent differences in transmittance for glucose and cytosine HCL, making this cuvette design a promising new tool for detecting protein conformations by THz-TDS.
There are some sources of uncertainty and misunderstanding in the process of material parameter extraction by THz Time Domain Spectrometry (THz-TDS) that are not initially evident. This paper aims to analyze the most common mistakes in interpreting THz-TDS measurements. Experimental evidence is shown where relevant.
