In the technet, on Mar1/96 by Ralph Hersey from Lawrence Livermore National

Laboratory on High Frequency Transmission Lin; it says now industry is

using seed which is later than copper then plate copper on top of it.

But this is a high freq. performance killer if the magnetic permeability

is greater than 1.

I do not understand the reason for this. Could anyone explain this to me?
