## Abstract

A magnetic measurement of the bar shaped test specimen placed inside the planar sensor is presented. A magnetic material characterization approach using planar cavity is proposed in this work. The proposed planar sensor relaxes the main limitations of conventional approach by using the proper feeding section. The proposed sensor is numerically verified using the full wave EM simulator for the magnetic property estimation. It is found that the developed sensor is able to characterize the test specimen with improved accuracy than that of conventional approach.
