Gain Enhancement Strategies in Wireless RF Energy Transfer

on 02-12-2022


IEEE and Instituto de Telecomunicações are inviting Professor Swades De for a second lecture dedicated to the theme "Gain Enhancement Strategies in Wireless RF Energy Transfer".

Wireless sensor nodes are characterized by limited energy sources. Although the interest in wireless connectivity is ever-increasing and the needs for Internet-of-Things (IoT) applications, such as automated remote access, monitoring, and control are well-appreciated, widespread adoption of networked wireless devices is largely constrained by their affordable deployment and maintenance costs and convenience of their long-term usage. To this end, while energy-efficient protocol design is a key for long-lasting network operation, energy harvesting-aware solutions are becoming widely popular as green and affordable approaches towards sustainable network operation. Since ambient energy harvesting is not reliable or suitable for many field applications, an interesting approach is charging them via wireless energy transfer. In this presentation, we will discuss the limitations of radio frequency (RF) energy transfer, the performance of multihop RF energy transfer, and some of the use cases of RF energy transfer combined with wireless information transfer. In particular, we will discuss the possible ways of improving RF energy transfer efficiency through passive and active distributed beamforming. Throughout the presentation, we will mutually corroborate our experimental findings and analytical intuitions in a few application scenarios.

Swades De is a full professor at the Department of Electrical Engineering and an Institute Chair Professor at Indian Institute of Technology Delhi. Dr. De's research interests are broadly in communication networks, emphasizing performance modeling and analysis. Current directions include energy-harvesting communication networks, broadband wireless access and routing, network coexistence, smart grid networks, and smart IoT. He has published over 230 articles in top journals and well-known conferences, a few book chapters, an edited book, 1 US/EU/WO patent, and filed 9 Indian patents and 6 US/EU/World patents. He, currently, serves as an Area Editor for IEEE Communications Letters, Area Editor for Elsevier Computer Communication, and Associate Editor for IEEE Transactions on Vehicular Technology, IEEE Wireless Communications Letters, and IEEE Wireless Communications Magazine.

This lecture is sponsored by IEEE Communications Society, IEEE Vehicular Technology Society and IEEE Instrumentation and Measurement Society and co-sponsored by Instituto de Telecomunicações.
