Abstract:
An example logging tool includes a tool body characterized by a longitudinal axis and an antenna coupled to the tool body. The logging tool further includes a ferrite element coupled to the tool body proximate at least a portion of the antenna and in a non-parallel orientation with respect to a normal of a plane defined by the antenna.
