Spatial filtering magnetic metasurface for misalignment robustness enhancement in wireless power transfer applications

HIGHLIGHTS

SUMMARY

As reported in the "Introduction", the purpose of this study is to demonstrate the ability to improve the misalignment robustness of a WPT system by employing a magnetic metasurface able to homogenize the magnetic_field distribution produced by a closely placed driving coil. By starting from the analyses developed ­in58, a uniform current distribution within the metasurface elements is the ideal configuration for generating a homogeneous magnetic_field over a larger area in the near field region. (N + 2) By opportunely selecting the current coefficients ci, any magnetic_field distribution can be ideally synthesized by spatially filtering . . .
