✦ Synopsis

Graphs of relative uncertainty for the s and s of hexaferr r ˜rite samples measured in a waveguide medium and retrieved from S-parameters using the NRW algorithm were presented, together with a discussion on error reduction when measuring the magnetic and dielectric properties of hexaferrites by controlling some experimental factors and limitations. The expected reflection loss range was derived based on the material properties and its uncertainties.

Because of cost restrictions, experiments were conducted in a guided-wave medium, and the reflectivity curves obtained can be considered a good starting point for designing practical hexaferrite absorbers.

It was found that the sample fit inside the waveguide is the primary source of measurement errors, and air gap corrections can only be ignored for gaps smaller than 30 m in the H-plane; otherwise, such simplification will lead to significant errors in the final results.
