NON-GAUSSIAN BEAMS FOR LONG-DISTANCE WIRELESS POWER TRANSMISSION

摘要

Systems and techniques are disclosed herein for generating and using Whisper Beams for wireless long-distance power transmission. For example, a radiofrequency (RF) Whisper Beam can focus high energy at great distances, which enables the technology disclosed herein to provide a practical means of transferring high power in a variety of applications and use cases. In some implementations, a method includes configuring an antenna to transmit two or more coherent out-of-phase Gaussian beams along a propagation axis to generate a beam of electromagnetic energy. The beam can be generated to propagate along the propagation axis, form a focus along the propagation axis, and has an intensity along the propagation axis that is less than a highest intensity of the beam off the propagation axis.
