Resonators for wireless power transfer systems

We review the recent advances in modern wireless power transfer (WPT) resonators design described in details in a review paper: M. Song et al. Applied Physics Reviews, vol. 4, 021102, (2017). Resonators play an important role in magnetic resonant WPT systems. Conventional resonators are based on metallic coils. We show how these resonators are evolving aiming at the miniaturization and compactness. On the other hand, we introduce a new kind of resonators made from dielectric materials. The WPT performance and medical application of such resonators are discussed.
