This would be the C3=0 case that I mentioned in the last post. L2 and
the
terminal would have to be totally enclosed in a cage. Capturing 50% of
the capacitance is quite easy. A magnifier equivalent would include
a transformer (L1-L2) to drive the influence plane, and an extra 
capacitor connected to the plane (C2) for correct tuning:

                                 (=====) Terminal
                                    |
                                    L3
                   k12              |
    o------+--C1--+   +-----+---(=) | (=) Influence plane
           o      |   |     |       |
   PSU    gap     L1  L2    C2      |
           o      |   |     |       |
    o------+------+---+-----+-------+-o Ground 

This system can be designed for higher gain and faster energy transfer
than the simpler version. Tuning is more complicated, however.
It's curious to note that the transformer of this magnifier
can be replaced by a capacitive transformer too (a capacitor between
the tops of L1 and L2)!

The base of L2 is grounded in the picture and in the schematic. With
a courier font, or any other fixed-width font, the drawing aligns 
perfectly. If you can't configure your mail reader to do this, cut
the picture from the text and paste it in Windows Notepad to see it.
