Extraction of effective parameters of double omega shaped metamaterial (Extraction des parametres effectifs dʹune structure metamateriau sous la forme « double omega »

The metamaterials are composites structures based on the assembly of magnetic resonators and infinitely long metal rods at sub-wavelength scale, however there are some other structures which exhibit the same behavior, in particular the structure "double omega", subject of our study. The extraction of effective parameters by the method of reflection-transmission coefficients demonstrates the metamaterial behavior of the said structure.
