Emerging technologies for long-range microwave-based power beaming
Half Day Workshop
Tuesday, 7 January, 13:00 - 16:00

Workshop Instructor(s): Ifana Mahbub, Email: Ifana.mahbub@utdallas.edu. Adnan Basir Patwary, Email: adnanbasir.patwary@utdallas.edu.

Course Abstract: Wireless power beaming (WPB) is a revolutionary direction in the development of the next generation of far-field wireless power transfer (WPT) networks since this approach yields increased range, enhanced signal gain, and increased power transfer efficiency. This short course discusses methods to increase efficiency in a WPB system that can be achieved by decreasing the loss occurring due to the propagation or the path loss, misalignment, and signal phase incoherence. A WPB system requires precise directive radiation beam which can be achieved using beamforming. This workshop discusses the transmitter (TX) and receiver (RX) antennas to achieve such directive radiation beam using beamforming while achieving a high gain and radiation efficiency. Antennas/metasurfaces with array elements are used for beamforming where the phase and amplitude along the array elements are adjusted to achieve a narrow directive beam as beam steering. The RX size and placement is determined strategically based on the TX beamforming performance and the RX distance from TX to improve the efficiency by achieving higher beam collection. The received power at the RX can be harvested using a highly efficient rectifier-based energy harvesting circuit. The workshop includes methods to improve the efficiency and range of WPB systems having singe TX-RX structure along with a distributed WPB systems.
