Abstract

The main steps for characterization and measurement of microwave absorbent materials in the 1-10 GHz range is introduced. The coaxial reflection-transmission type of material parameter measurement is analyzed in detail and the main measurement error is corrected. The microscopic material particle parameter measurement concept is also presented using different mixing rule laws to determine the material parameters of the single particles from the macroscopic parameters. Two dimensional FDTD simulations have been used to model the behavior of mixed electric and magnetic type of material.
