How to select resonant wireless coil?

Im a new player of wireless transmission. And Im searching some manuls or guides about coil searching.

Hello Mewesther,

Welcome to the community!

Forgive me, could you please explain what type of application you’re looking for more information on?

Thank you!


I am trying to design wireless energy transmission through RLC series resonance, but I have not touched this field before. So I have no idea of the selection of coils, such as the material, coil shape, and other matters. As a result, I want to find some information online.

And I have looked for some coils on the Internet, but I found that they were all marked with Qi standard, the largest inductance was only 47uH. I am not sure if there are larger inductance?
