1. A method for wirelessly powering a medical device that is adapted to be disposed within a living subject, the method comprising the steps of:

  • generating a radiofrequency energy field in a first direction from a first position outside said living subject, said radiofrequency energy field extending into said living subject to energize said medical device; and

    from a second position outside said living subject opposite to said first position from which said radiofrequency energy field is generated, reradiating in a second direction opposite to said first direction, at least a portion of said radiofrequency energy field such that said radiofrequency energy field is generally uniformly distributed between the first position and the second position.
