摘要： An apparatus is described that selectively absorbs electromagnetic radiation. The apparatus includes a conducting surface, a dielectric layer formed on the conducting surface, and a plurality of conducting particles distributed on the dielectric layer. The dielectric layer can be formed from a material and a thickness selected to yield a specific absorption spectrum. Alternatively, the thickness or dielectric value of the material can change in response to an external stimulus, thereby changing the absorption spectrum.

摘要： Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.

摘要： The present invention provides conduit assemblies of substantial length that have an inner member disposed in an opening of a conduit member and connected to the interior of the conduit member. The inner member can serve to protect sensitive measuring equipment, such as optical sensors or well logging equipment, from damages, including damages incurred during deployment into subsurface environments, including oil and gas wells and oceans, while allowing for improved data collection by the equipment once deployed. The conduit assemblies can be deployed permanently or as intervention logging equipment. The present disclosure also provides for methods of making and using such conduit assemblies.

摘要： The disclosure relates to an apparatus for insertion of a conduit into a well system bore to introduce a reactant fluid over a subterranean catalyst to initiate decomposition of the reactant fluid which resultant energy release may be utilized to perform work or perform heating of the subterranean environment. The reaction may be further accelerated by the addition of a fuel down into the reaction chamber or blended with the reactant fluid at a surface location. Reaction products can be jetted from a reaction chamber orifice against the proximal surface of the well system bore which may be either a production zone for the purpose of stimulating production or against a casing to perforate the casing and expose the production zone adjacent such perforation. The energy released from said catalytic reaction and subsequent combustion of fuels may also be used for cutting, welding, powering pumps, compressors, turbines, generators, or to heat well system fluids, pipes, subterranean reservoir fluids, subterranean solids, and completion devices in the well system.
