Terahertz Technology for Communication and Sensing

Dear Colleagues,

Terahertz (THz) technology, operating in the 0.1–10 THz frequency range, has attracted significant attention for its transformative potential in both communication and sensing applications. With ultra-high data rates and wide bandwidths, THz communication systems are expected to play a critical role in enabling next-generation wireless networks. Moreover, THz waves possess unique properties—such as the ability to penetrate a variety of materials, non-ionizing radiation, and distinct spectroscopic signatures—making them particularly well suited for sensing applications in healthcare, security, environmental monitoring, and industrial inspection.

While THz technology holds immense promise, several challenges persist, including signal attenuation, limited transmission range, and the need for efficient devices and components. Addressing these challenges requires innovations in THz transceivers, antennas, waveguides, and integrated systems. Advances in spectroscopy and imaging techniques further broaden the scope of THz applications, providing insights into material properties and enabling non-destructive testing.

This Special Issue aims to serve as a platform for researchers to present recent breakthroughs in THz communication and sensing. Contributions are invited on topics including, but not limited to, THz transceivers, antennas, and waveguides; high-speed wireless networks, THz spectroscopy and imaging; non-destructive testing and material characterization; integrated sensing and communication systems; and advanced materials and device fabrication.

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. Electronics is an international peer-reviewed open access semimonthly 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 2400 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.
