Abstract
Various methods and systems are provided for a current trap. In one example, the current trap has a flat core made of a nonconductive material, a coiled wire having a plurality of turns winding around the flat spiral core, and one or more tuning capacitors physically attached to the flat core and electrically connected to the coiled wire to form a resonant circuit with the coiled wire.
