Summary:
This paper presents an improved technique of dielectric-property determination of a material under test using magnitudes of associated scattering parameters of two different coupled parallel dipoles to avoid possible non-unique solutions and to enhance the accuracy of predicted solutions. Measured results are plotted on the εr'εr'' plane, scaling with simulated magnitudes of associated scattering parameters, to determine εr' and εr'' of the material under test, where εr' and εr'' are the real and imaginary parts of its complex relative permittivity, respectively. It is found that non-unique solutions can be avoided using the improved technique, and the accuracy of predicted solutions can be practically improved using the additional information obtained from the improved technique..
