We present a method for extracting the magnetic parameters of a soft magnetic Co-based alloy (Co/sub 68.25/Fe/sub 4.5/Si/sub 12.25/B/sub 15/) in the high-frequency regime (100 MHz-2.5 GHz). The method uses the magnetic sample (as-cast ribbon) as the conductor of a terminated microstrip transmission line. It uses the complex propagation constant of the line… CONTINUE READING
