Theoretical and experimental effective parameters of metamaterial substrate

The inversion and the field summation methods are used to determine the effective permeability and permittivity of metamaterial structure. The S-parameters (for ldquoInversion Methodrdquo) and the field calculator (for ldquofield summationrdquo) simulated using commercial software are used to extract the effective parameters. A simple technique to realize a metamaterial substrate is proposed in this paper. A sample of metamaterial substrate is realized and measured. The results are compared to the simulation results obtained with the both methods (inversion and the field summation). The good agreement was found.
