Abstract

In this work we demonstrate an open resonator powered for the first time by a frequency-comb locked continuous wave terahertz spectrometer. A sample of a 10 μm thin cling film is placed into the resonator, leading to shifts and attenuation of resonance frequencies, and proving the sensitivity of our instrument to low-absorbing, low-permittivity materials.
