摘要
Original approach to near field magnetic resonance wireless power transfer using high permittivity dielectric resonators is presented. The results of numerical simulation and experimental investigation of the wireless power transfer systems based on spherical dielectric resonators with the permittivity epsilon=80 and disk dielectric resonators with the permittivity epsilon=1000 are reported. For the wireless power transfer system based on spherical resonators operating at magnetic dipole mode and magnetic quadrupole mode the maximal efficiency of 60% and 80% is verified experimentally in GHz frequency range. The wireless power transfer system based on disk dielectric resonators with the permittivity epsilon=1000 operates at the frequency of 220 MHz and provides 50% efficiency at 7 cm resonator separation. The test with a real load is also performed.
