Abstract
A contactless power transfer system is proposed. The power transfer system comprises a field-focusing element comprising a dielectric material. The dielectric material comprises a composition that is selected from the family of (Ba,Sr)TiO3 or CaCu3Ti4O12. The compositions of the (Ba, Sr)TiO3 include the materials such as Ca1-x-yBaxSryTi1-zCrzO3-δNp, wherein 0<x<1; 0<y<1; 0≦z≦0.01; 0≦δ≦1; and 0≦p≦1. The compositions of the CaCu3Ti4O12 include the materials such as Ca1-x-yBaxSry(Ca1-zCuz)Cu2Ti4-δAlδO12-0.5δ, wherein 0≦x<0.5; 0≦y<0.5; 0≦z<1; and 0≦δ≦0.1.
