摘要： Energy efficient noise dampening coaxial and twisted pair cables include certain layers to improve the quality of signals transmitted over the cables. A coaxial cable includes a conductive core, a first insulating layer surrounding the conductive core, a metal shield layer surrounding the first insulating layer, a second insulating layer surrounding the metal shield layer, a carbon material layer surrounding the second insulating layer, and a protective sheath wrapping the carbon material layer. A twisted pair cable section includes a core section. The core section includes a carbon material core, an insulating layer surrounding the carbon material core, and a metal shield layer surrounding the insulating layer. A plurality of twisted pair cables are disposed in sections or compartments defined by the core section, and between the core section and a protective sheath. Methods for constructing the cables are also disclosed.

摘要： A carbon fiber composite, including a carbon fiber not connected to a substrate, an insulative layer coating at least a portion of the carbon fiber, and a material deposited on at least a portion of the insulative layer. The carbon fiber deposit may be used, for example, in adjustable Fresnel lenses and horn antennas.

摘要： An antenna apparatus includes an electrically conductive section having peripheral edges, an antenna element coupled to the electrically conductive section, which transmits or receives electromagnetic signals, and an electromagnetic absorbing carbon material component. The carbon material component is generally disposed adjacent to the electrically conductive section, and includes a border region extending beyond the peripheral edges of the electrically conductive section. The carbon material component can be constructed of a carbon fiber fabric in which the carbon fibers are arranged to increase the effective signal to noise ratio of the antenna apparatus and enhance antenna performance without increasing the baseline power consumption level. The carbon fibers can be coated with silicone to insulate them externally while enhancing their lengthwise conductivity.

摘要： A carbon fiber composite includes a carbon fiber not connected to a substrate, an insulative layer coating at least a portion of the carbon fiber, and a material deposited on at least a portion of the insulative layer. A method for forming a carbon fiber composite includes electrostatically applying a plurality of carbon fibers to a substrate, coating each of the carbon fibers with an insulative material, depositing a material onto a least a portion of the insulative material of each of the carbon fibers, and dissolving the substrate to release each of the carbon fibers.

摘要： A noise dampening tape and gasket material for reducing or preventing unwanted electromagnetic interference from escaping or entering an enclosure. The noise dampening gasket includes an inner core section, a carbon material layer surrounding the inner core section, an insulating layer surrounding the carbon material layer, and a metal shield layer surrounding the insulating layer. The noise dampening tape includes a metal shield layer, an insulating layer adjacent to and in contact with the metal shield layer, a carbon material layer adjacent to and in contact with the insulating layer, and an adhesive layer disposed on a surface of the carbon material layer. A second adhesive layer can be disposed on a surface of the metal shield layer. The carbon fibers can be coated with silicone or polytetrafluoroethylene to enhance mechanical and electrical properties of the carbon material layer.
