Improving the efficiency of magnetic coupling energy transfer by etching fractal patterns in the shielding

Qing-feng LI,Shao-bo CHEN,Wei-ming WANG,Hong-wei HAO,Lu-ming LI

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1,   Pages 74-82 doi: 10.1631/FITEE.1500114

Abstract:

Thin metal sheets are often located in the coupling paths of magnetic coupling energy transfer (MCETEddy currents in the metals reduce the energy transfer efficiency and can even present safety risks.Fractal pattern slots in multilayer high conductivity metals (e.g., Cu) reduce the induced magnetic fieldFurthermore,transfer power, transfer efficiency, receiving efficiency, and eddy current losses all increaseThese results can benefit MCET by efficient energy transfer and safe use in metal shielded equipment.
