Colossal permittivity dielectric resonators for magnetic resonant wireless power transfer systems are proposed. The wireless power transfer system based on two dielectric resonators with the permittivity ε=1000 operating at the frequency 230 MHz is established. Numerical simulation and experimental investigation of the WPT system efficiency are performed. The measured efficiency of 50% is achieved at separation between the resonators d=16 cm (3.8 radii of the resonator). The power transfer… CONTINUE READING
