Special Issue Information

Dear Colleagues,

The global average monthly mobile data consumption rate is expected to reach 24 gigabytes per user by 2025. The current wireless communication infrastructure cannot sustain such future demands. Terahertz (0.1 – 100 THz) communication is an obvious and indeed a viable option to develop high bandwidth point-to-point wireless links.

Although the THz systems that include sources, modulators, and detectors are being actively developed, the technology is not yet as mature as the microwave and optical frequency counterparts. The development of THz systems is in fact a multidisciplinary effort, in which the knowledge of the atomic structure of the materials dictate the desired electronic and radiation characteristics. In this regard, THz technologies need to be developed by physicists, chemists, material scientists and electronic engineers. We devote this special issue to the multidisciplinary facets of the development of THz technologies for future wireless communications.

This special issue is focused on the latest and state of the art THz technologies that can help to finally unlock the true potential of THz waves. We invite original scientific research articles that deal with the experimental, theoretical, and simulation-based studies on THz technologies. A list of relevant set of topics is provided below, yet other topics are also welcome:

  • THz technologies for future wireless communications
  • THz antennas and systems
  • Two-dimensional materials
  • THz sources and detectors
  • Nanotechnology based device fabrication
  • Plasmonics
  • Electromagnetic analysis and design of THz systems
  • Plasmonic technologies
  • Photonic and optical techniques for THz
  • System on chip
  • Integrated antennas

To meet the increasing need of high-data-rate and broadband wireless communication systems, the devices and its circuits R&D under Millimeter, Sub-Millimeter, or even Terahertz (THz) frequency bands are attracting more and more attention from not only academic, but also industrial areas. Most of the former research on the THz waveband (0.1–10 THz) antenna design is mainly focused on realizing high directional gain, such as horn antennas, even though the coverage area is very limited when comparing with the current Wi-Fi system. One solution for the horizontally omnidirectional communication antenna is using the structure of multiple split-ring resonators (MSRRs). Aiming at this point, a novel 300 GHz microstrip antenna array based on the dual-surfaced multiple split-ring resonators (DSMSRRs) is proposed in this paper. By employing the two parallel microstrip transmission lines, different MSRRs are fed and connected on two surfaces of the PCB with a centrally symmetric way about them. The feeding port of the whole antenna is in between the centers of the two microstrip lines. Thus, this kind of structure is a so-called DSMSRR. Based on the different size of the MSRRs, different or multiple working wavebands can be achieved on the whole antenna. Firstly, in this paper, the quasi-static model is used to analyze the factors affecting the resonance frequency of MSRRs. Simulation and measured results demonstrate that the resonant frequency of the proposed array antenna is 300 GHz, which meets the design requirements of the expected frequency point and exhibits good radiation characteristics. Then, a dual-band antenna is designed on the above methods, and it is proved by simulation that the working frequency bands of the proposed dual-band antenna with reflection coefficient below −10 dB are 274.1–295.6 GHz and 306.3–313.4 GHz.
