A system for harnessing and conditioning wirelessly transmitted electrical energy by near field magnetic induction configured with various magnetic field shielding embodiments is disclosed. The shielding embodiments are designed to minimize electromagnetic interference and induced electrical current. The system comprises an electrical energy capture circuit and an RF communication circuit. The electrical energy capture circuit conditions and modifies the wirelessly received electrical energy. The RF communication circuit enables the system to wirelessly communicate with its sub-circuits and other energy capture systems. The system comprises a tunable band stop filter that is electrically connected to the RF communication sub-circuit. In addition, the RF communication sub-circuit is configured with opposing electrically conductive plates that isolate and shield the circuit from an oscillating magnetic field.
