摘要:
In accordance with the present invention, an aperture rectenna is provided where the substrate is transparent and of sufficient mechanical strength to support the fabricated structure above it. An aperture antenna is deposited on the transparent substrate and a metal-insulator-metal (MIM) diode is constructed on top of the aperture antenna. There is an insulating layer between the aperture antenna metal and the metal ground plane optimized to maximize the collection of incident radiation. The top of the structure is capped with a metal ground plane layer, which also serves as the DC connection points for each rectenna element.

摘要:
A method and system for generating power from low- and mid-temperature heat sources using a zeotropic mixture as a working fluid. The zeotropic mixture working fluid is compressed to pressures above critical and heated to a supercritical state. The zeotropic mixture working fluid is then expanded to extract power. The zeotropic mixture working fluid is then condensed, subcooled, and collected for recirculation and recompression.
