Hi All, I saw in some papers that the coupling factor k of two wireless power coils (L1 and L2) equals to M/SQRT(L1*L2), while M is the mutual inductance of these two coils. I am wondering if there is any method we can use to measure this M when the two coils are placed at a certain distance (say, 1cm in the perfect alignment condition). I do not have the vector network analyzer, is it possible for me to do this measurement in the lab? Both L1 and L2 are known since they are commercial available products.
Thank you!
