On one side, millimeter-wave and terahertz bands are emerging as the most promising solution to meet the data-rate and latency demands of future wireless applications, including virtual reality and autonomous cars. On the other side, the large spectral availability, together with the mm-scale wavelength, opens the opportunity of ubiquitous and high-resolution sensing. My research builds a foundation for joint communication and sensing in such high-frequency regimes yielding a paradigm shift in the design and development of future wireless systems.

In this talk, I will present the world’s first single-shot and single-antenna motion-sensing system in THz bands. We demonstrate a novel node architecture exploiting a single leaky-wave antenna, which is primarily used for beam steering in THz networks. I will explain how we leverage this device’s spatial-spectral characteristics in new ways to enable motion sensing functionalities with a single THz pulse transmission. I will then discuss the opportunities offered by this platform to enhance next-generation communication in unprecedented ways. In particular, we tackle the mobility, blockage, and scalability challenges of highly directional THz networks by efficiently adapting steering direction.

Finally, I will share with you some of the exciting research directions I would like to pursue in the future. I am broadly interested in exploring novel fundamental concepts and new devices that enable sensing functionality jointly with networking in a broad scope of applications. This interdisciplinary research direction incorporators advancements such as applied physics, machine learning, robotics, and wireless networking.
