Abstract
A transmission element for a downhole tool comprising an annular housing and an annular ferrite channel within the annular housing. An annular nonlinear coil may be disposed within the annular ferrite channel, and the nonlinear coil may be connected to a cable running within the downhole tool. The housing may be an annular groove or recess within the tool, an annular metal trough, or an annular polymeric block. The polymeric block may comprise a composite of a polymer and a volume of ferrite elements comprising Fe and Mn. The annular nonlinear coil may comprise a wave, a helix, a twisted pair of wires, a transformer comprising a coil and a metal core, or a combination thereof. The polymeric block may comprise and bumper on its periphery and a void opening within the block proximate the bumper. The ferrite channel and the coil may be molded within the polymeric block.
