Usually, the practical application of a wireless power transfer (WPT) system handles power of several watts to several thousand watts. The power used in WPT is much larger than that in wireless communication, therefore there are strong concerns from society regarding WPT applications’ safety. In this research, from the viewpoint of dispelling social concerns about the safety of WPT system, we attempted to visualize the electromagnetic field of the WPT system by combining electromagnetic field analysis, measurement technology and augmented reality AR (Augmented Reality) technology. At last, this research will help to grasp the distribution of electromagnetic fields around the WPT system in real time to accelerate the spread of the WPT technology and make the users to confirm the safety of the WPT system.

A approach was developed to calculate the scattering matrix of the antennas in the near-field wireless power transfer system in a complex environment by using the method of moments to design the system with the maximum power transfer efficiency, Loosy matching circuits were successfully designed to improve the impedance matching condition. A method was proposed to compensate the change of input impedance of the antennas to solve the problem of efficiency reduction due to the change of the relative distance and position between the transmitting and receiving antennas in the system. In the proposed system, a parasitic array with a impedance switch in each array element is electrically controlled.

This research makes it possible to implement moment method algorithm in GPU which was ever required by using the super computer with the very expensive cost. The developed moment method algorithm takes into account the large scale numerical analysis with the dielectrics. Definitely, it is hopeful that our electromagnetic analysis of a large model and acceleration algorithm can be applied to a lot of larger scale applications, such as a new artificial electromagnetic materials, space power generation systems, and communication, scattering / radiation problems including people, cars, ships and planes, and so on
