In general, the extraction of parameters of an EM system having a non-trivial geometry is obtained by measurement with field solver simulator tools, which intrinsically use iterative processes, instead of making a mathematical analysis that would hardly be able to give this result in the form of an explicit function for this parameter.
I'm not very familiar with this segment of electronics, but the little I've seen from this tool I found it very powerful for a free sofftware and perhaps you could take some results with it..Can you suggest me some program that does this measurement?

Exactly, although as usual we aim to be accurate in the modeling of the phenomenon, the mathematical complexity is always such that at certain stage we are tempted to simplify it with specific assumptions (eg: wire gap much smaller than coils distance, etc ...), which ends loosing part of the general characteristic of the solution.Calculation will give you an insight but simulation will be much more realistic
You've got 4 ports.Download Sonnet EM simulator for free and find the couplings and other stuffs by simulation.

Can you suggest an EM simulator tool just to measure coupling,loss of two inductors (wireless transmission) with distance, turns and frequency.
