Metamaterials for Wireless Power

Powering devices wirelessly is currently a major topic of interest. Metamaterials have the potential to make wireless power transfer easier and more efficient in a number of different ways. In an analysis just published by our group in the Journal of Applied Physics, written in collaboration with colleagues at the University of Washington and Intellectual Ventures (more details here), we describe how a dynamically tunable metamaterial antenna could be used to beam focused power to devices for small and medium distances. The illustration above depicts a single metasurface panel beaming power to numerous devices.
