Hey Dave, I'm new to this forum, and I just wanted to say your wireless charger project is very interesting. I just had a couple questions. Say, your primary coil had a large diameter like yours. Could you fit two identical secondary coils inside the middle with their respective parallel resonance circuits, and be giving power to two different applications? I imagine, if that's possible, the amount of power going to the secondary circuits would be split in half?

Additionally, would the resonant frequency be affected at all?
