LDC1614EVM: calculation of total inductance from target interaction

Part Number: LDC1614EVM
Other Parts Discussed in Thread: LDC1614

Hello everyone,

I am planning work with LDC1614 eval board with a custom planar coil.  Now I am dealing with calculation of inductance of coil as well as influence of target distance to total inductance. LDC_Tools-ext51 provide these information, but cells are locked so I can not see equations and I would like to better understand. I found many equations to calculate inductance of coil from geometry, but not for relation between coil an conductive target. Do you have some papers that dealing with calculation of total inductance according distance of target. 

Regards,

Frantisek
