Convertible transmission-reflection time-domain terahertz spectrometer
Abstract
The creation of reliable instrumentation for performing complex reflectance and transmittance measurements of dielectrics, metals, and superconductors in the frequency range from 60 GHz to 1.5 THz is reported. The system allows continuous variation of the THz radiation incidence angle from 25° to 80° without major realignment of the optics and provides the signal-to-noise ratio of 1000:1.

Existing experimental techniques to circumvent phase sensitivity in reflection geometry are often material-specific and cannot be universally applied to all sample types.
“Despite their effectiveness, these techniques often tend to be material-specific and cannot be universally applied to all sample types.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
