Graphene-coated coupling coil for AC resistance reduction

Title: Graphene-coated coupling coil for AC resistance reduction

Abstract

At least one graphene layer is formed to laterally surround a tube so that the basal plane of each graphene layer is tangential to the local surface of the tube on which the graphene layer is formed. An electrically conductive path is provided around the tube for providing high conductivity electrical path provided by the basal plane of each graphene layer. The high conductivity path can be employed for high frequency applications such as coupling coils for wireless power transmission to overcome skin depth effects and proximity effects prevalent in high frequency alternating current paths.

Method and apparatus for identifying conductive objects by monitoring the true resistive component of impedance change in a coil system caused by the object

Patent Gregory, William D [Vienna, VA]; Capots, Larry H [McLean, VA]; George, James P [Falls Church, VA]; ...

The type of conductor, its property, and if a metal, its type and cross-sectional area can be obtained from measurements made at different frequencies for the amount of unbalance created in a previously balanced stable coil detection system. The true resistive component is accurately measured and thus reflects only the voltage loss attributable to eddy currents caused by introduction of the test sample to the coil system. This voltage divided by corresponding applied frequency gives a curve which peaks at a frequency dependent upon type of conductor. For a metal this peak frequency is proportional to the samples resistivity dividedmore » by its cross-sectional area.« less
