University of Maryland Gemstone Team TESLA had a very successful time at the 2016 IEEE Wireless Power Transfer Conference May 5-6, 2016 in Aveiro, Portugal. This international conference brought together the leading experts in the emerging technology of providing wireless power to everything from TV remotes and cell phones to electric vehicles. Three of the 10 team members are physics majors: Scott Roman, Tyler Grover and Ben Philip. Roman and Frank Cangialosi represented the team at the conference. Both gave invited talks, and with their mentor Steven M. Anlage, presented a poster on their concept for a wireless power transfer system based on time-reversed electromagnetic waves. Anlage, a Professor of Physics, a member of CNAM and a Faculty Affiliate in ECE, was recently named a UMD Distinguished Scholar-Teacher.
Gemstone Team TESLA has spent the last three years investigating basic questions related to a radical new method to deliver wireless power to devices in an enclosed environment. Their idea is to harness the time-reversal properties of wave propagation to deliver microwave energy to a precise location in space. This energy is then rectified and used to power the device. Team TESLA has carried out a series of experiments and simulations to show that this technology is feasible, and they have developed new ideas to overcome some of the challenges that the technology faces.
The talks (and associated papers and US patent applications) were:
Time Reversed Electromagnetic Wave Propagation as a Novel Method of Wireless Power Transfer, by Frank Cangialosi, Tyler Grover, Patrick Healey, Tim Furman, Andrew Simon, Steven M. Anlage. This work has resulted in an invention disclosure PS-2016-011 made to the UMD Office of Technology Commercialization on 14 February, 2016. “Method of Delivering Power to a Moving Target Wirelessly via Electromagnetic Time Reversal”. A provisional US Patent Application was filed on 25 April, 2016, Application No.: 62/327,346.
Selective Collapse of Nonlinear Time Reversed Electromagnetic Waves, by Scott Roman, Rahul Gogna, Steven Anlage. This work has resulted in an invention disclosure PS-2016-012 made to the UMD Office of Technology Commercialization on 14 February, 2016. “Selective Collapse of Nonlinear Time Reversed Electromagnetic Waves”. A provisional US Patent Application was filed on 25 April, 2016, Application No.: 62/327,349.
The poster presentation was entitled Time-Reversed Electromagnetic Wave Propagation as a Novel Method of Wireless Power Transfer, by Frank Cangialosi, Anu Challa, Tim Furman, Tyler Grover, Patrick Healey, Ben Philip, Scott Roman, Andrew Simon, Liangcheng Tao, and Alex Tabatabai. The associated paper won the Best Paper Award for the entire conference (about 200 submissions). The award includes a framed certificate, a book from Cambridge University Press, and a €400 cash award.
