Effect of air-gap between metal strips and a ferrite plate on magnetic shielding

In this paper, the effect of air-gap between the metal strip and ferrite plate on magnetic shielding in the presence of a periodic line current source is analyzed in two-dimensional and approximate model of the WPT coils in electric vehicles and mobile devices. An analytical method based on Fourier transform and mode matching technique is proposed to investigate the penetration of quasistatic magnetic field into the ferrite plate and metal strips.
