Abstract

An extraction algorithm has been proposed for explicit complex permittivity and complex permeability determination of samples using reference-plane-invariant scattering parameters without resorting to the application of the passivity principle. The algorithm relies on the definition of new odd and even reflection coefficients which result in no-crossing of the negative real axis for the argument of the square-root functions. Permittivity measurements of two low-loss samples were performed for validation of our algorithm. Published by AIP Publishing.
