Topic Information

Dear Colleagues,

The terahertz (THz) band is envisioned as one of the key technologies in supporting 6G smart lives in the future, where the biophysical world and digital world will be integrated with an intelligent connection between everything. Its characteristics, such as small device size, strong sensing ability, ultra-high data rate up to Tbit/s, and high security at the physical layer, demonstrate its potential for the integration of sensing and communication (ISAC). By unitizing software and/or hardware resources (waveform, spectrum, antenna, system, etc.), THz ISAC has shown its unique superiority in improving communication efficiency and perceptual sensitivity (positioning enhancement, posture recognition, etc.) with low resource consumption. This proposed Topic aims to capture the latest advances in terahertz techniques for the integration of sensing and communication. Review and original research articles on theoretical methods, applicative techniques, as well as new advanced methodologies for relevant scenarios, are very welcome. We hope that, by reading this Topic, that readers will understand how the terahertz band can be applied in sensing, communication and other fields.

The potential topics include, but are not limited to: Terahertz ISAC system designs; Transceivers and components for terahertz systems; New device technologies, architectures, and demonstrators for terahertz ISAC systems; Terahertz antenna systems and arrays; Ultra-massive MIMO architectures and control algorithms; Waveform design and beamforming for terahertz ISAC; THz imaging, positioning/localization, and THz spectroscopy; Ultra-broadband digital signal processing architectures and algorithms; Terahertz channel propagation and models; Health risks and evaluation for terahertz illumination; AI-assisted terahertz ISAC system design and application.

In order to meet the increasing demand of non-destructive testing (NDT) in engineering practice, a continuous terahertz NDT platform based on linear scanning has been developed, with a center frequency of 154 GHz and a bandwidth of 56 GHz. This system combines frequency modulation continuous wave (FMCW) radar technology with a continuous scanning structure, as well as a data acquisition platform to provide a non-contact detection method; this is highly efficient and compensates for the shortcomings of traditional methods such as microwave, X-ray, ultrasonic, and others in safety inspection and special detection. In addition, a signal processing method of spectral refinement and correction is proposed in this paper for accurate thickness measurement. The results show that the method has a high accuracy for ABS, PVC, and ceramic matrix composites. By extracting the characteristic parameters, the detection and imaging of prefabricated defects, such as debonding and bubbles in composite materials, have been successfully achieved. This helps to evaluate the internal state of the inspected object more intuitively and further meets the requirements of industrial NDT. Full article

One of the most important problems in the plasmonics of the terahertz (THz) range, which is actively developing now, is the efficient generation of surface plasmon polaritons (SPPs). The simplest and most promising technological technique of photon excitation of THz SPPs is through diffraction of radiation on the edge of the conducting surface of the sample (the end-fire coupling technique). In this paper, we experimentally evaluated the efficiency of the generation of monochromatic THz SPPs (λ0 = 141 μm) by this method with a sample in the form of a cylindrical segment, the convex surface of which has a gold layer coated by zinc sulfide (ZnS) with thickness d = 0–2 µm. Such configuration of the surface supporting the SPPs not only shields the detector from parasitic bulk waves arising during diffraction but also enables one to change the distribution of the SPP field in the air by varying the coating layer thickness d. On an uncoated gold surface, the SPP generation efficiency was η ≈ 20%. In the presence of a ZnS layer on the gold, the SPP generation efficiency gradually increased with d, reached the maximum (ηmax ≈ 60%) at d ≈ 1 μm, and then gradually decreased. Theoretical analysis showed that the efficiency of the SPP generation can be raised up to 80% due to the selection of an optimal SPP field profile via variation of the thickness of the dielectric layer on the metal surface, as well as with optimal incidence of the focused radiation on the edge of the sample.

This paper presents a compact hybrid G-band (170–260 GHz) heterodyne receiver module incorporating both Millimeter Microwave Integrated Circuits (MMICs) and a Schottky diode-based circuit. An on-chip sextupler and a Low Noise Amplifier (LNA), along with a diode-based Sub-Harmonic Mixer (SHM), are integrated into the demonstrated singular module, which is carefully designed and arranged with the co-simulations in electromagnetic and thermal domain. Through this methodology, a terahertz receiver module is fabricated with a volume of only 27 × 20 × 20 mm3. The measured results indicate that the double-sideband conversion gain of the receiver is 10.5–17.5 dB from 195 GHz to 230 GHz, while the noise temperature is 1009–1158 K. As a result, this terahertz receiver provides recorded miniaturized hardware applicable for terahertz Integration of Sensing and Communication (ISAC) systems. Full article
