摘要： Passive radiative cooling panels are produced by anodizing an aluminum foil sheet to form metamaterial nanostructures and then forming a plated metal over the metamaterial nanostructures to produce an ultra-black emitter, and then securing a reflective layer (e.g., a solar mirror film) onto the ultra-black emitter. The process is implementable in a roll-to-roll-type fabricating system in which a continuous aluminum foil ribbon extends from a feed roll through an anodization station to a reflector mounting station such that a first ribbon section undergoes anodization while a second ribbon section undergoes plating and a reflective layer is mounted onto a third ribbon section. A modified Anodic Aluminum Oxide (AAO) self-assembly technique is utilized to generate tapered nanopores that are then plated to generate an ultra-black emitter capable of generating broadband radiant energy with an emissivity close to unity. Modules are produced by mounting the panels onto conduit structures.

摘要： A passive radiative cooling system in which an ultra-black emitter includes metamaterial nanostructures disposed on the top surface of a metal sheet, and a conduit structure channels the flow of coolant against a bottom surface of the metal sheet. The metamaterial nanostructures (e.g., tapered nanopores) are configured to dissipate heat from the coolant in the form of emitted radiant energy having wavelengths/frequencies that fall within known atmospheric transparency windows (e.g., 8-13µm or 16-28µm), the emitted radiant energy being transmitted through a reflective layer into cold near-space. The ultra-black emitter is formed using a modified Anodic Aluminum Oxide (AAO) self-assembly technique followed by electroless plating that forms metal-plated tapered nanopores, and the reflective layer includes a distributed Bragg reflector. The cooling system is made scalable by way of modular cooling units (modules) that are configured for connection in series and parallel to form dry cooling systems suitable for large power plants.

摘要： A low-cost passive radiative cooling panel includes an emitter layer disposed under an upper reflective layer, where the emitter layer includes metamaterial nanostructures (e.g., tapered nanopores) configured to dissipate heat in the form of radiant energy that is transmitted through the reflective layer into cold near-space. In an embodiment the emitter layer includes ultra-black material configured to emit, with an emissivity close to unity, radiant energy having wavelengths/frequencies that fall within known atmospheric transparency windows (e.g., 8-13µm or 16-28µm). In a practical embodiment the emitter layer is formed using a modified Anodic Aluminum Oxide (AAO) self-assembly technique followed by electroless plating that forms metal-plated tapered nanopores. The reflective layer includes a distributed Bragg reflector configured to reflect at least 94% of incident solar light while passing the emitted radiant energy, and in some embodiments is implemented using a low-cost, commercially available solar mirror film.

摘要： A radio frequency (RF) energy harvesting device (rectenna) includes an antenna structure configured to resonate at RF frequencies, and a rectifying circuit that facilitates harvesting multiband RF signals having low energy levels (i.e., tens of mW and below) by utilizing two Zero Bias Schottky diodes having different forward voltage and peak inverse voltage values. Positive voltage pulses from a captured RF signal generated on a first antenna end point are passed by the first diode to a first internal node where they are summed with a second RF signal generated on the second antenna end point (i.e., after being passed through a capacitor), thereby producing a first intermediate voltage having a substantially higher voltage level. Positive voltage pulses are then passed from the first internal node through the second diode to an output control circuit for conversion into a usable DC output voltage.
