Paper Abstract
In this contribution, we present the employment of a Genetic Algorithm (GA) based procedure to retrieve the effective
permittivity and permeability of planar metamaterial samples. The approach used here is the same of standard
Transmission/Reflection (TR) techniques, consisting in extrapolating the sample properties by inversion of its scattering
coefficients. The proposed procedure makes use of parametric models for describing the inherently dispersive behavior
of the involved materials. This approach eliminates the anomalous behavior of most of the commonly used inversion
techniques, providing a consistent representation of the material in the working frequency range. The transition to bulk
effective parameters is also investigated determining a proper sample thickness assuring the validation of the
homogenization procedure.
