In this paper, an improved technique of using
open-ended rectangular waveguide sensor for
simultaneous non-destructive complex electromagnetic
parameters determination of compound absorbing
materials is developed. The technique is based on
employing a layered material medium, which consists of
material to be tested and known materials, sandwiched
between sensor aperture and perfect conductor plate to
obtain two complex reflection coefficients necessary to
achieve this purpose. Finite-Difference Time-Domain
method is adapted to account for the finite flange size of
the sensor and numerically calculate the sensor reflection
coefficient under different test conditions. The technique
can be employed for cases of single layer and multilayer
medium planar sheet measurement. The parameters of the
material under test are obtained by fitting both the
calculated and measured reflection coefficients using the
iterative optimization technique. The details related to the
analysis, FDTD modeling and testing procedure of the
proposed technique is discussed. The simulations and
experimental results are compared with the published data
by literatures and companies to validate the proposed
technique. The technique is promising for potential
applications such as design and fabrication of sheet or
layered coating materials and nanocomposite material and
bio-medium characterization
