Abstract
A thermal barrier for a wireless power transfer system comprises a first surface area () for coupling to a power receiver () to be powered by a first electromagnetic signal and a second surface area () for coupling to a power transmitter () providing a second electromagnetic signal. The thermal barrier () further comprises a power repeater () with a resonance circuit including an inductor and a capacitor. The power repeater () is arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards the first surface area (). The thermal barrier may provide thermal protection of the power transmitter () without unacceptable impact on the power transfer operation.
