Is there a relation between the mutual inductance across a pair of bifilar wound coils, and the inductance per meter of the same winding considered as a transmission line? I.e., can one calculate one from the other?
This is a very confusingly worded question. Which "inductance per meter" did you mean? Ref @Baluncore's distinction of common mode vs. differential mode. Maybe a sketch would be in order, or a clear identification with standard jargon about which inductances you meant?Swamp Thing said:Is there a relation between the mutual inductance across a pair of bifilar wound coils, and the inductance per meter of the same winding considered as a transmission line?

The twisted pair impedance is really determined by wire diameter and insulation type/thickness. More twists simply shorten the wavelength at which the twisted pair will operate without radiative losses.Swamp Thing said:Yet intuitively, it seems that changing something (eg twist per cm or insulation thickness) that reduces the L/m would also push the K nearer to 1.
