  "textContent": "A transformer system is provided that includes four magnetically coupled coils having fixed spacing geometry. The four magnetically coupled coils include a drive coil that produces magnetic fields and a load coil. A first resonant coil is magnetically coupled to the drive coil producing energy that is stored by the first resonant coil. A second resonant coil is magnetically coupled to the first resonant coil to propagate the energy stored in the first resonant coil to the second resonant coil without using a magnetic core. The second resonant coil is then magnetically coupled to the load coil where the energy is transferred to the load coil.",
