Calculating Theoretical Transfer Efficiency for Wireless Energy System

[redhot2k4]

Homework Statement

I have built a wireless system as described at the following site http://www.ar2r.50webs.com/wte/wte.html"

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??

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

Cheers

redhot2k4,

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.
