UTICA, NY – SUNY Polytechnic Institute Assistant Professor of Electrical and Computer Engineering Dr. Arjun Singh and peers recently published three pieces of research.

The first, titled “Ultrabroadband Terahertz-band Communications with Self-healing Bessel Beams,” is set to appear in the scientific journal, Nature. In it, they experimentally demonstrated that new wavefront designs (Bessel beams) can outperform conventional communication techniques with Gaussian beams for Terahertz systems. 

Dr. Singh and peers’ research titled, “Near-field 6G Networks: Why Mobile Terahertz Communications MUST Operate in the Near Field,” was accepted into the proceedings at GLOBECOM 2023, an elite global communications conference put on by the Institute of Electrical and Electronics Engineers (IEEE) that will take place in Malaysia this December. This research provides theoretical proof as to why mobile THz communications must happen in the near-field, which has been a subject of debate among researchers in the THz domain, recently. 

Dr. Singh and peers also collaborated on research titled, “Design and Validation of a Metallic Reflectarray for Communications at True Terahertz Frequencies,” that was accepted into the proceedings of the ACM Workshop on Millimeter-Wave and Terahertz Networks and Sensing Systems, which will take place later this year in Spain. This research is significant because it’s the first experimental demonstration of non-line-of-sight communications with broadband communication signals utilizing a reflectarray at true THz (> 1THz) frequencies. 

In addition to these newer research items, Dr. Singh and peers’ previous work on spectrum coexistence is the cover story of the August 2023 Proceedings of the IEEE issue.
