About

Professor Emmanouil 'Manos' Tentzeris is the Ed and Pat Joy Chair Professor in the School of Electrical and Computer Engineering at Georgia Tech. His research focuses on high-performance electromagnetic applications, particularly in the development of innovative wireless communication systems. Alongside Ph.D. candidate Marvin Joshi, he has contributed to the creation of a lens-enabled backscatter system capable of multi-gigabit data rates, reaching up to 4 Gbps while operating with minimal power consumption. This system leverages a dielectric lens to focus millimeter-wave energy onto tiny antenna elements, enabling high-speed, energy-efficient wireless communication without traditional transmitters. Professor Tentzeris's work demonstrates how advanced lens technology can overcome limitations of conventional backscatter systems, allowing for high data rates over wide angular coverage and distances up to 20 meters. His research aims to enable battery-free sensors and devices that can be deployed at scale in smart city infrastructure, disaster response, and other applications, providing fiber-like performance in a wireless, energy-efficient manner. His ongoing efforts include moving from proof-of-concept to real-world deployment, integrating these systems into mobile platforms and infrastructure, and exploring AI-based optimization to enhance system performance.
