Patent ID: 7919961

Claim:
A method for measuring magnetic permeability of a magnetic material by measuring the magnetic interaction of an electromagnetic field with this material by using a measuring device including a measuring cell connected through a microwave frequency cable to a vector network analyser, said method comprising: preliminary steps for gauging/calibrating said measuring device, determining corrective coefficients to be applied to the measurements obtained by means of this device, verifying the non-drift of this device, these steps being carried out with the help of a reference sample, a step for measuring the permeability of the magnetic material, wherein, during the preliminary steps, a reference sample is used, comprising at least one inclusion which enables creation, in a given volume, of a local artificial permeability, each inclusion being achieved by combining at least one inductive component associated with a combination of at least one capacitive and/or resistive and/or active component, the frequency response of the electromagnetic properties of each volume being adjusted by the value and the assembly architecture of the components, and in that the value of at least one component of at least one inclusion is remotely adjustable.
