The vibrational characteristics of gas hydrates are key identifying molecular features of their structure and chemical composition. Density functional theory (DFT)-based IR spectra are one of the efficient tools that can be used to distinguish the vibrational signatures of gas hydrates. In this work, ab initio DFT-based IR technique is applied to a...

The energy level separation between the edge states in topological insulator quantum dots lies in the terahertz (THz) range. Quantum confinement ensures the nonuniformity of the energy level separation near the Dirac point. Based on these features, we propose that a topological insulator quantum dot array can be operated as an electrically pumped c...

Two graphene-based tunable coding metasurfaces are proposed for beam steering in terahertz band. The coding metasurfaces are composed of the unit cell with a sandwich-like structure, which contains the top layer of anisotropic rectangular graphene structure, intermediate dielectric layer and ground plane. The designed metasurfaces can be dynamicall...

The efficiency of photo-conductive switches, which continue to be used for the generation and detection of THz waves, has been overlooked for a long time. The so far 'optics-dominated' devices are making their way through to new and emerging fields of research that require ultrafast picosecond voltage pulses, as well as to new applications where po...

The interaction of monocycle terahertz (THz) fields with metal nanostructures such as nanotips is attracting a lot of interest for the development of new applications such as THz-scanning tunneling microscopy and ultra-fast field emission. New methods have been introduced to measure the enhanced THz near field waveform in the vicinity of a nanotip ...

Broadband, quantum-engineered, quantum cascade lasers (QCLs) are the most powerful chip-scale sources of optical frequency combs (FCs) across the mid-infrared and the terahertz (THz) frequency range. The inherently short intersubband upper state lifetime spontaneously allows mode proliferation, with large quantum efficiencies, as a result of the in...

The next generation of connected and autonomous vehicles will be equipped with high numbers of antennas operating in a wide frequency range for communications and environment sensing. The study of 3D spatial angular responses and the radiation patterns modified by vehicular structure will allow for better integration of the associated communication...

There is an increasing recognition that terahertz (THz) spectroscopy can be used for high-sensitivity molecular sensing. Therefore, in recent years, much work has been devoted to developing flexible, compact, and high-sensitivity THz sensors. However, most designs employ metamaterials, which require complicated, and often expensive, fabrication pro...
