Terahertz and Millimeter Wave Communications for 5G and Beyond: Applications and Future Directions

Dear Colleagues,

The emergence of terahertz (THz) and millimeter wave (mmWave) technologies is revolutionizing wireless communication systems, enabling unprecedented data rates, ultra-low latency, and massive connectivity. These advancements are crucial for realizing and shaping the future of wireless network applications beyond 5G (B5G) and toward 6G. However, several research questions remain unanswered regarding propagation and channel modeling, hardware limitations, the use of spectrum, network and protocol implementation, antenna design, security and privacy, and the role of AI in optimizing the integration between THz and mmWave systems.

In light of the unprecedented interest in this field, this Special Issue explores innovative research on THz and mmWave communication systems. We invite high-quality, original contributions that focus on, but are not limited to:

• THz and mmWave channel modeling, propagation, and measurements.
• Performance analysis of THz and mmWave communication systems.
• Network architectures and protocols.
• Novel antenna design and beamforming techniques.
• Advanced modulation, coding, and signal processing strategies.
• AI/ML for integration of THz and mmWave systems.
• Cyber and physical-layer security of THz and mmWave networks.
• Spectrum sharing, coexistence, and interference management.
• Testbeds, experiments, and prototyping of THz and mmWave systems.
• Standardization, regulatory, and business frameworks for THz and mmWave systems.
• New applications and use cases for THz and mmWave systems.

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. Sensors 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 2600 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.
