Embodiments provide a method for determining an alternating magnetic field (AMF) transmitter design that produces a magnetic field that achieves a more uniform surface current or heating of an implant. Embodiments may utilize the method to be applicable to different geometries of implants and AMF transmitters. Embodiments produce a non-uniform magnetic field that in turn produces a more uniform current density / distribution on the implant surface. This leads to uniform heating and consistent biofilm reduction, while minimizing damage to adjacent tissues. Also, the differences in electrical properties such as conductivity, permittivity, and permeability of the implant components can be factored into the design process to achieve a uniform current density / distribution across components. An ultimate benefit derived from embodiments described herein is consistent biofilm reduction, inactivation, eradication, destruction, and / or removal and improved safety arising from heat conduction into surrounding tissues.
