Modified Broadband Magnetic Characterization Technique using Planar Cavity

A broadband magnetic measurement of the bar shaped test specimen placed along the width of cavity is presented. A unified closed form relationship complying with the planar SIW technology is first time proposed in this work. The proposed formulations basically relax the main limitations by using the proper modification of perturbation formulation. The proposed formulation is firstly numerically verified using the full wave EM simulator for the magnetic property estimation of magnetic materials. It is found that the developed formulation is able to characterize the test specimen with improved accuracy than that of conventional cavity perturbation approach.
