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

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 (MCETThe fractal patterns should satisfy three features, namely, breaking the metal edge, etching in the high-intensitymagnetic field region, and etching through the metal in the thickness direction.These results can benefit MCET by efficient energy transfer and safe use in metal shielded equipment.
