Computation of Power Beaming Efficiency in the Fresnel Zone with Application to Amplitude and Phase Optimization
Abstract
A MATLAB program capable of calculating the efficiency of a wireless power transfer system is described. The scripts operation is based upon an equation derived from the Huygens-Fresnel principle, which was discretized for use in a numerical solution. The software's user interface and outputs are briefly outlined, with specific features explained separately. Transfer efficiency improvement via phase focusing and amplitude optimization is also discussed. These features are explained and demonstrated using a simulation test case. Finally, comparison is drawn with existing efficiency data.
