Nondestructive Characterization of PEC-Backed Materials Using the Combined Measurements of a Rectangular Waveguide and Coaxial Probe
A novel one-port probe technique, which combines the measurements of a rectangular waveguide and coaxial probe to nondestructively yield the permittivity and permeability of a PEC-backed material, is presented. A brief description of the derivation of the theoretical probe reflection coefficients, necessary for permittivity and permeability extraction via numerical inversion, is provided. Experimental characterization results of a PEC-backed magnetic material are presented to validate the proposed approach. Error analysis is also undertaken to quantify the new technique's sensitivity to common experimental errors. Abstract © IEEE.
