Multiple Folding Coils Design for Octagonal Prism-Based Wireless Charging Container with Even Magnetic Flux Density Distribution

This paper presents an octagonal prism-based wireless charging container with multiple folding coils winding equidistantly around the surface of the container. The optimal coefficient for the equant ratio has been identified to be 1/7 for achieving a more even distribution of magnetic flux compared to the conventional design of the octagonal prism-based wireless charging container. This advancement enables omnidirectional wireless charging for multiple dynamic receivers with minimal power fluctuations.
