Dynamic and Efficient RF Lens for Wireless Power Transfer over Long Distances

Abstract

Through the past few years, there has been a dramatic increase in the number of small electronic devices available on the market. All of those devices need to be powered by some means, which is usually facilitated through the use of a cord plugged into the device. Users, however, may wish to use their device without being restricted by a cord. Wireless power makes it possible to deliver power without needing to plug a device in. In addition, allowing users to move their device away from the charging apparatus allows for a better user experience. Through radio frequency lensing, this thesis looks at how it is possible to deliver power at a distance in order to be harvested by a device.
