A non-eddy current electro-magnetic interference (EMI) shield to prevent or inhibit generation of eddy currents in the shield. The shield may include a non-conductive enclosure, one or more conductive traces interlaced on the non-conductive enclosure, wherein the one or more conductive traces do not form any conductive loops, and one or more ground connections on the one or more conductive traces, wherein the one or more ground connections do not form a ground loop. The EMI shielded electronic device may at least partially encompass an electronic device, such as a magnetic tracker, wherein the EMI shield comprises a non-conductive housing, with conductive traces interlaced on the housing, in a pattern or arrangement such that the conductive traces do not form any conductive loops. One or more ground connections may be provided for the one or more conductive traces.
