Abstract

The microwave dielectric and magnetic properties of carbonyl iron powders were investigated using the waveguide technique. The experimental results of the complex permittivity and permeability of these carbonyl iron powders are presented. The complex permeability of these carbonyl iron powders are quite similar due to their high content of iron while the complex permittivity of the carbonyl iron powders are different, classifying the various contents of the samples.
