The spectrometer consists of a thermal infrared emitter with near-ideal blackbody radiation characteristics and a low-noise pyroelectric detector. A filter bank with 16 narrow band-pass optical coating filters is selected to define a coarse set of 16 discrete spectral data points between 20 to 80 THz. Both transmission and reflection modes of operation are demonstrated `over the THz horizon' (within the extended THz range). This work shows the potential of this emerging low-cost technology for non-destructive and non-invasive testing, material characterization, material identification from a pre-characterized database, process variation monitoring and gas sensing.

The strong confinement of the terahertz field in combination with the high Q-factor provided by the PCR allows the measurement of the dielectric properties of sub-nanoliter liquid volumes. We demonstrate the utility of this approach by measuring the complex permittivity of several bio-liquids at 100 GHz.
