Permeability Determination of Metallic Wires by a Method Combining Measurement and Computer Simulation

Abstract

This work is to present a method combing measurement and computer simulation techniques to determine the relative permeability of metallic wires. By constructing a test bed on which the wire under evaluation, it is used to form a two-wire transmission line. The permeability is found out when its set value in the simulation model offers the same simulated characteristic impedance with the measured one on the test bed by a TDR (Time-Domain Reflectometry).
