Detection of sugar solution at low concentration using terahertz spectroscopy combined with frequency-selective surface (FSS) by Ishak, Nurul Syafeeqa

“…Terahertz (THz) technology has sparked the interest among researchers to explore the terahertz radiation. However, low detection sensitivity has become the main concern in terahertz spectroscopy in which led to discovery of improvement on limited detection sensitivity by using Frequency Selective Surface (FSS) that provided by the high electric-field concentration in the spatial filtering in FSS. …”

Ultrafast photo-thermal switching of terahertz spin currents by Agarwal, Piyush, Medwal, Rohit, Kumar, Abhishek, Asada, Hironori, Fukuma, Yasuhiro, Rawat, Rajdeep Singh, Battiato, Marco, Singh, Ranjan

“…Femtosecond light pulse provides an ideal pathway for exciting the ferromagnet (FM) out-of-equilibrium, causing ultrafast demagnetization and superdiffusive spin transport at sub-picosecond timescale, giving rise to transient terahertz radiation. Concomitantly, light pulses also deposit thermal energy at short timescales, suggesting the possibility of abrupt change in magnetic anisotropy of the FM that could cause ultrafast photo-thermal switching (PTS) of terahertz spin currents. …”

Retrieval of terahertz ice cloud properties from airborne measurements based on the irregularly shaped Voronoi ice scattering models by M. Li, M. Li, H. Letu, H. Ishimoto, S. Li, L. Liu, T. Y. Nakajima, D. Ji, H. Shang, C. Shi

“…As an application, we used the inversion algorithm to retrieve the ice cloud IWP and <span class="inline-formula"><i>D</i>_me</span> based on the Compact Scanning Submillimeter-wave Imaging Radiometer (CoSSIR) airborne terahertz radiation measurements. Validation against the retrievals of the Bayesian algorithm reveals that the Voronoi ICS model performs better than the sphere and hexagonal column ICS models, with enhancement of the mean absolute errors of 5.0 % and 12.8 % for IWP and <span class="inline-formula"><i>D</i>_me</span>, respectively. …”
