1. A wireless energy source compatible with multiple energy transfer techniques comprising:

  • an amplifier, configured to operate at a first frequency and a second frequency;

    a first energy transfer element, configured for wireless energy transfer using a first energy transfer technique at the first frequency; and

    a second energy transfer element, configured for wireless energy transfer using a second energy transfer technique at the second frequency;

    wherein the second frequency is different than the first frequency, andwherein the impedance of the first energy transfer element at the first frequency is less than the impedance of the first energy transfer element at the second frequency.
