Special Issue Information

Dear Colleagues,

The scientific research and industrial applications dealing with the terahertz spectrum of electromagnetic waves have been growing at a fast pace in the recent years. Previously being represented mainly in the field of deep space observation of the background radiation, it has now expanded to security, health screening, and short-range communication. The “terahertz gap” in the technology of generating, detecting, and operating with terahertz radiation is quickly populating with new components, developments, and paradigms. There is a range of new compact powerful terahertz sources and sensors. The research spans to terahertz metamaterials, neo-fieled terahertz technology, and high-resolution terahertz spectroscopy and microscopy. This Special Issue is intended to report recent advances in new innovative solutions, components, and algorithms related to terahertz technology.

Articles in this Special Issue will address topics that include: novel terahertz sources and sensors; terahertz metamaterials; terahertz spectroscopy and neo-filed imaging, microscopy; technologies for short-range communication; terahertz components for extreme environments; and application of terahertz technology for security and health screening.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Technologies 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 1600 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.

In the past year, fifth-generation (5G) wireless technology has seen dramatic growth, spurred on by the continuing demand for faster data communications with lower latency. At the same time, many researchers argue that 5G will be inadequate in a short time, given the explosive growth of machine connectivity, such as the Internet-of-Things (IoT). This has prompted many to question what comes after 5G. The obvious answer is sixth-generation (6G), however, the substance of 6G is still very much undefined, leaving much to the imagination in terms of real-world implementation. What is clear, however, is that the next generation will likely involve the use of terahertz frequency (0.1–10 THz) electromagnetic waves. Here, we review recent research in terahertz wireless communications and technology, focusing on three broad topic classes: the terahertz channel, terahertz devices, and space-based terahertz system considerations. In all of these, we describe the nature of the research, the specific challenges involved, and current research findings. We conclude by providing a brief perspective on the path forward.
