Poziv na predavanje: "Wireless Power, Seamless Design: Energy Harvesting Antennas --- the Future of Self-Sustaining Devices"

Abstract

Can antennas do more than transmit and receive? As the demand for autonomous, battery-less devices grows across IoT, biomedical, and remote sensing applications, wireless energy harvesting has emerged as a transformative solution. At the heart of this innovation lies the energy harvesting antenna—an element that not only captures electromagnetic waves but converts them into usable power.

This talk explores the design, integration, and application of antennas engineered for wireless energy harvesting. We will examine the fundamental trade-offs in antenna efficiency, bandwidth, and rectification, and discuss how novel materials, multi-band structures, and co-design with rectifiers are enabling compact, high-performance systems. From far-field energy harvesting to near-field wireless power transfer, these antennas are redefining how devices are powered in constrained environments.

As we move toward a future of trillions of connected devices, the ability to harvest energy from ambient waves may redefine how we think about power itself—not as a constraint, but as an opportunity embedded in the electromagnetic fabric of our environment. This talk invites researchers to rethink the role of antennas—not just as conduits of communication, but as gateways to sustainable, self-sufficient electronics.    

Short Bio

Arup Ray (Member, IEEE) received the B. Tech. and M. Tech. degrees in Electronics & Instrumentation and Communication Engineering from the University of Kalyani, India. He earned his Ph.D. degree in 2022 from Indian Institute of Technology (IIT) Kharagpur. His dissertation focused on the design methodologies and integration challenges of on-chip antennas with RF front-end circuits such as low-noise amplifiers (LNAs) and rectifiers. In 2022, Dr. Ray joined Qualcomm India Private Limited, Bangalore, as a Senior Engineer. He is currently working as a Senior Lead Engineer in the RFIC team. His work involves electromagnetic modeling, RF component design, and coupling mitigation at chip and package level, with a focus on innovation and performance optimization. He has contributed to three novel ideas at Qualcomm, all of which have been filed as U.S. patent applications.

Dr. Ray is a corporate member of the IEEE and the Institution of Engineers (India). He has been actively involved in IEEE activities, having served as Chair of the IEEE AP-MTTS Student Branch Chapter at IIT Kharagpur. He has authored or co-authored nine journal papers and three conference papers in the areas of RFIC design, antenna integration, and electromagnetic simulation. In addition to his research contributions, he has served as a peer reviewer for several international journals, including IEEE Antennas and Wireless Propagation Letters,  IEEE Transactions on Components, Packaging and Manufacturing Technology, Springer Scientific Reports, IETE Journal of Research, and IET Microwaves, Antennas & Propagation.
