IEEE President K. J. Ray Liu, “Follow Multiple Paths,” Changing the World With Microwave Time Reversal Focusing

Abstract

This is the sixth in our Microwave Pioneer series in which we are privileged to provide our readers with a very special subject: current IEEE President K. J. Ray Liu. Professor Liu's inclusion in this series is not due to his position as leader of the IEEE, but rather to his influence and leadership in the field of indoor surveillance and tracking using microwaves. His discovery, demonstration, and application, of microwave multi-path time reversal focusing for use in positioning and tracking, when coupled with recent advances in wireless communications, are primed to have worldwide impact. The imminent roll-out of commercial systems through Professor Liu's company, Origin Wireless AI, could change the very nature of our society through its many potential applications in indoor monitoring, tracking, and motion sensing using existing Wi-Fi infrastructure. The implications for both improved security and health care in the home and office – as well as the accompanying controversies over issues of privacy, are profound. It is appropriate that an individual who has already had a considerable role in shaping our local signal processing and microwave fields, as well as the broader IEEE community, should extend his influence to our society at large. With 12 books, 18 book chapters, 6 special issue journal releases, more than 800 refereed journal and conference publications, over 70 patents and dozens of editorials and magazine pieces, you will certainly appreciate Professor Liu's multi-path impact as you read about his multi-path career!
