Abstract
An inspection system includes an electromagnetic shield having electrically conductive sidewalls spaced from one another. The shield also includes a conductive third wall which spans the distance between the sidewalls, and is electrically coupled to the sidewalls. The inspection system also has an inductive sensor positioned within the electromagnetic shield. The inductive sensor has two current branches, which exhibit anti-symmetric current flow. Typically, the two current branches are positioned on opposing sides of the medial plane of the electromagnetic shield.
