Abstract
An electromagnetic core assembly for power and data transmission in a tool string for downhole construction and production comprising an annular mesh housing defining an annular open channel. A magnetically conductive electrically insulating, MCEI, core is disposed within the annular open channel. An annular electrical conductor is imbedded within the MCEI core, the electrical conductor being connected to ground and to a cable running through a downhole tool. The mesh housing may be at least partially electrically insulating and at least partially electrically conducting. The mesh housing may comprise a metal or a nonmetal or a fabric. The mesh housing may comprise MCEI elements. The mesh size of the housing may be sufficient to at least partially contain an electromagnetic field or flux emanating from the electrical conductor. The MCEI core may comprise a depression in its planar top surface above the electrical conductor. The core may comprise reinforcements.
