Modelling of negative equivalent magnetic reluctance structure and its application in weak-coupling wireless power transmission

Yuanxi Chen,
Shuangxia Niu,
Weinong Fu
et al.

Abstract: In weak-coupling wireless power transmission, increasing operating frequency, and incorporating metamaterials, resonance structures or ferrite cores have been explored as effective solutions to enhance power efficiency. However, these solutions present significant challenges that need to be addressed. The increased operating frequency boosts ferrite core losses when it exceeds the working frequency range of the material. Existing metamaterial-based solutions present challenges in terms of requiring additional … Show more
