Hi All, I have a 13.56MHZ wireless power transfer system. In this system, there is also the data link operating at the other frequency.
I was trying to use the flexible shielding material to minimize the noise coupling from the power coil to data coil. However, if I use the material to cover the power Rx coil, it will block the power transfer from Power Tx coil, and there is no power supply of the board.

I am using the co-plane structure for the Rx coils. The picture is shown here.

The flexible shielding material (for 13.56MHz shield) comes from here https://katalog.we-online.de/en/pbs/WE-FSFS . Would anyone teach me where should I place the material? Thank you very much!
 

you want to set it up something like this I believe

Also make sure you tune your system with the shielding in the way, it will alter your coil L and Q.
