A contactless 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)TiO 3 or CaCu 3 Ti 4 O 12 . The compositions of the (Ba, Sr)TiO 3 include the materials such as Ca 1-x-y Ba x Sr y Ti 1-z Cr z O 3-´ N p , wherein 0 < x < 1; 0 < y < 1; 0 ‰¤ z ‰¤ 0.01; 0 ‰¤ ´ ‰¤ 1; and 0 ‰¤ p ‰¤ 1. The compositions of the CaCu 3 Ti 4 O 12 include the materials such as Ca 1-x-y Ba x ,Sr y (Ca 1-z CU z ,)CU 2 Ti 4-´ Al ´ O 12-0 . 5´ , wherein 0 ‰¤ x < 0.5; 0 ‰¤ y < 0.5; 0‰¤ z ‰¤ 1; and 0 ‰¤ 8 ‰¤ 0.1. |
