Abstract: A solar vapor generator includes an absorber to absorb sunlight and an emitter, in thermal communication with the absorber, to radiatively evaporate a liquid under less than 1 sun illumination and without pressurization. The emitter is physically separated from the liquid, substantially reducing fouling of the emitter. The absorber and the emitter may also be heated to temperatures higher than the boiling point of the liquid and may thus may be used to further superheat the vapor. Solar vapor generation can provide the basis for many sustainable desalination, sanitization, and process heating technologies.

Abstract: A reconfigurable triplexer that can support more frequency bands than a traditional triplexer is disclosed. For example, the reconfigurable triplexer can handle frequencies of several hundred megahertz up to 10 gigahertz. Further, certain implementations of the reconfigurable multiplexer can reduce or eliminate frequency dead zones that exist with traditional multiplexers. The reconfigurable triplexer includes a multi-stage filter bank capable of supporting a number of frequency bands and a bypass circuit that enables the triplexer to support a variety of sets of frequencies. For instance, unlike traditional triplexers, the reconfigurable triplexer can support both frequency bands with relatively narrow spacing and frequency bands with relatively wide spacing. Further, the inclusion of the bypass circuit enables the reduction or elimination of dead zones between supported frequencies.
