Abstract
A method of forming a short-hop communications transceiver includes creating, in a conductive tool body, an annular cavity that is electromagnetically coupled to an external tool surface by a surface gap that encircles the tool body. The method further includes positioning material having high magnetic permeability in the annular cavity. The method further includes coupling electrical leads from an electronics module to opposite sides of the surface gap. The method further includes operating the electronics module to perform short-hop telemetry by driving or sensing a voltage signal across the surface gap.
