一种测量复射频磁导率的成熟方法是基于在插入一个环形样品时同轴传输线的电感和电阻的变化。不需要在环形样品上绕线圈，也不需要校正几何退磁因子。如本文所述，使用现代商用阻抗分析仪使得在1千赫兹到1吉赫兹范围内的测量特别容易、快速且准确。
An established method for measuring complex rf magnetic permeability is based on the change in inductance and resistance of a coaxial transmission line upon insertion of a sample toroid. It is not necessary to wind coils on the toroid or correct for geometric demagnetization factors. The use of modern commercial impedance analyzers, as described in this paper, makes measurements from 1 kHz to 1 GHz particularly easy, fast, and accurate.
