Abstract

Here we present a silicon based, micro-machined fluidic device for terahertz frequencies, fabricated using standard lithographic and micro-machining processes in a cleanroom environment. Designed for use in a conventional transmission terahertz time-domain spectroscopy (THz-TDS) arrangement, we present a possible solution to the ‘water problem’ currently hampering the analysis of aqueous and biological systems at THz frequencies. We detail results from a range of experiments, highlighting the device sensitivity and potential, wide-ranging applications.
