We performed THz time-domain attenuated total reflection spectroscopy of arginine and sucrose solution, and verified that this method gives us reasonable hydration numbers.
The 2D THz photonic bandgap structures are fabricated of cured SU-8, and installed in single mode metal parallel plate waveguides. The structures are characterized by THz time-domain spectroscopy. The experimental measurements agree with theoretical predictions.
We present a terahertz radiation detector that measures both transverse components of a terahertz single cyclepsilas electric field, allowing the study of polarization dependent properties of materials. Measurements of birefringence in quartz are presented.
We present a novel design of a high-temperature multipass cell for laser-based spectrometers. Its performance is demonstrated with mid-infrared spectral measurements on hot bands of methane and on condensed compounds in the vapor phase.
We demonstrate terahertz time-domain attenuated total reflection spectroscopy of various organic powder samples, which is useful for convenient and repeatable characterization of the materials such as biomolecules.
