Wireless power transfer in attenuating media

Dissipative media (underground/underwater, biological materials and tissues, etc.) pose a challenge to inductive wireless power transfer systems as they generally attenuate the near fields that enable mutual coupling. Apart from this, impact of environment on electromagnetic can also be seen in self-impedance coils, resulting significant eddy current losses detuning effects. In this article, we study, theoretically, mechanism via pair magnetic resonators inside an infinite homogeneous medium with comprehensive circuit model takes into account all effects background medium. This analytical approach offer deep insights design operation charging non-ideal environments.
