Broadband Terahertz Devices and Communication Technologies, 2nd Edition

Dear Colleagues,

The Recommendation Framework for IMT-2030 (Global 6G Vision) was completed by the International Telecommunication Union (ITU-R) radio communication division in 2023. Multiple frequency ranges will be needed to meet the capacity and coverage requirements and to serve emerging services and bandwidth-consuming Internet applications. The wireless traffic volume is foreseen to be sufficient to match or even surpass wired services by 2030, and the high-precision wireless services will need to be guaranteed with a peak data rate of well beyond 100 Gbit/s, eventually 1 Tbit/s. There has been ongoing academic and industry research and development related to the suitability of mobile broadband systems in frequency bands above 100 GHz. The terahertz band (0.1 THz-10 THz), sandwiched between microwave and optical frequencies, is considered the next breakthrough point to revolutionize communication technology due to its rich spectrum resources. It is recognized as a promising candidate for future rate-greedy applications, such as 6G communications. In the World Radio Communication Conferences 2019, identifying frequency bands in the frequency range 275 GHz–450 GHz was permitted for land-mobile and fixed services applications, with a total spectrum bandwidth of 137 GHz. In May 2024, the ITU-R approved a new Report about the “Technical feasibility of IMT in bands above 100 GHz”, which provides information in bands between 100 GHz and 400 GHz.

Motivated by the potential of terahertz wireless communications, this Special Issue seeks critical technology breakthroughs in terahertz communications. The Special Issue topics include but are not limited to, broadband terahertz devices, terahertz frontend and antenna design, baseband processing for THz links, terahertz propagation and channel modeling, system-level demonstration of terahertz communications, integrated sensing, and communication.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
