Extracting complex permeability from measured input impedance is performed based on the inductive behavior of the coaxial holder. Three numerical techniques based on non-uniform transmission line theory, frequency domain finite difference method, and 3D Method of Moments (MoM) are used to verify above methodology. The obtained results are discussed in detail.
