WebJan 1, 2016 · Here, we demonstrate the first multiheterodyne spectroscopy using two terahertz quantum cascade laser combs. Over a spectral range of 250 GHz, we achieve average signal-to-noise ratios of 34 dB using cryogenic detectors and 24 dB using room-temperature detectors, all in just 100 μs. WebApr 12, 2024 · Terahertz time-domain spectroscopy has been used to study the THz optical properties of polyvinyl alcohol–graphene oxide–silver (PVA–GO–Ag) composite films with varying weight fractions of silver nanoparticles in the range of 0.0–0.64%.
WebTo solve this issue, this paper utilizes machine learning (ML) to propose an absorption bandwidth and structural parameters prediction approach for the design of PGMA based on the random forest (RF) algorithm, which can reduce unnecessary numerical simulation and spectra analysis time. Web摘要： Recently we introduced a Sub-THz spectroscopic system for characterizing vibrational resonance features from biological materials. This new, continuous-wave, frequency-domain spectroscopic sensor operates at room temperature between 315 and 480 GHz with spectral resolution of at least 1 GHz and utilizes the source and detector …
