Highly Miniaturized Dielectric Layer Loaded Split Cavity Resonator for Wireless Power Transfer Applications

In this paper, a wireless power transfer scheme that exploits the electromagnetic induced transparency-like interaction between dielectric resonators and a dielectric layer loaded split cavity is proposed. By proper design, the thickness and the permittivity of the dielectric layer are chosen such that the fields inside the cavity are uniform, resulting in a 66 % reduction in the total volume when compared to the previously reported split cavity-based system.
