Abstract
In this paper, a Conductivity Invariance Phenomenon with a controlled lift-off is discovered and studied. It is found that at certain lift-off, the effect of conductivity influence on inductance is eliminated/reduced. Based on this phenomenon, a novel permeability measurement approach is proposed. The proposed approach was verified by both simulation and experimental data. And the permeability can be estimated in a reasonable accuracy (with an error of 2.86%) by the proposed approach without the influence of its conductivity.
