摘要：

We demonstrate a Fabry-Perot cavity for sensing highly absorbing liquids at terahertz frequencies. A sub-wavelength layer of liquid sample is accommodated between a ground plane and a silicon window. A probing terahertz pulse through the window can interrogate a minute change in the bulk properties of the sample. The sensing is manifested through a shift in the Fabry-Perot resonance. Importantly, this resonance can sustain high quality factor despite strong attenuation induced by the sample.
