Wireless transfer of energy

  1. Mar 30, 2010 #1
    1. The problem statement, all variables and given/known data
    I have built a wireless system as described at the following site http://www.ar2r.50webs.com/wte/wte.html" [Broken]

    I would like to be able to apply some theory to it and calculate a theoretical value for the transfer efficiency over certain distances

    Does anybody have any idea of the theory I would need to use??

    3. The attempt at a solution

    In a paper by Andre Kurs, "Power transfer through strongly coupled resonances" he derives a formula for transfer efficiency from coupled mode theory however it is complicated and the coils he uses are self resonant, where as mine have a raised capacitive plate making them an LC resonant circuit

    Any help would be greatly appreciated

    Would it matter whether the coil was self-resonant or not? The self-resonant inductors still use capacitance, but it's part of the coil... I would think you could use the same formula.
