  • Device for near field and far field imaging in the microwave range
    Patent number: 9797847
    Abstract: A device for the imaging of an object to be studied, combines: a prism made from a material with no losses (non-absorbent) for radiation in the microwave range; a sample holder on a front face of the prism for receiving the object to be studied; and a mobile emitting antenna on a rear face of the prism in order to emit radiation in the microwave range.

  • THERMOPHOTOVOLTAIC SYSTEM HAVING A SELF-ADJUSTING GAP
    Publication number: 20160142005
    Abstract: A thermophotovoltaic system for generating energy can include a photovoltaic cell, a radiator separated from the photovoltaic cell by a vacuum gap having a distance of less than 10 micrometers, and an actuator operably connected with at least one of the photovoltaic cell and the radiator to adjust the gap distance. A method of thermophotovoltaic energy conversion can include heating a radiator to produce infrared radiation, irradiating a photovoltaic cell with the infrared radiation to produce an electric current, maintaining a vacuum gap between the radiator and the photovoltaic cell with a gap distance of less than 10 micrometers, and dynamically adjusting the gap distance during irradiating based on a temperature of at least one of the radiator and the photovoltaic cell.

  • Cascaded Photovoltaic and Thermophotovoltaic Energy Conversion Apparatus with Near-Field Radiation Transfer Enhancement at Nanoscale Gaps
    Publication number: 20100031990
    Abstract: A cascaded photovoltaic/thermophotovoltaic energy conversion apparatus, a cascaded thermophotovoltaic energy conversion apparatus, and a method for forming the apparatuses are provided. The cascaded photovoltaic/thermophotovoltauc apparatus includes a photovoltaic device that receives solar radiation on an upper surface thereof and produces a first electric current output and a thermal radiation output, and a thermophotovoltaic device disposed a predetermined distance below a lower surface of the photovoltaic device, the thermophotovoltaic device receiving the thermal radiation output and converting the received thermal radiation output into a second electric current output.
