  • Heat-flux control and solid-state cooling by regulating chemical potential of photons in near-field electromagnetic heat transfer
    Publication number: 20160298882
    Abstract: Solid state near-field radiative cooling from a cold emitter to a hot collector is provided. Two cases are considered. In the first case, the cold emitter is forward biased to drive heat flow from the cold emitter to the hot collector. A surface resonance of the collector is configured to enhance this cooling effect. In the second case, the hot collector is reverse biased to control heat flow from the cold emitter to the hot collector. A surface resonance of the emitter is configured to enhance this cooling effect.

  • Wireless energy transfer
    Patent number: 9142998
    Abstract: Electromagnetic energy transfer is facilitated. In accordance with an example embodiment, a first resonator transmits electromagnetic energy using an electromagnetic wave, based on frequency matching and alignment of an electromagnetic field with a second resonator within a distance of one wavelength of the electromagnetic wave from the first resonator. An electromagnetic energy reflector adjacent the first resonator redirects reflected portions of the electromagnetic wave back towards the first resonator.
