Abstract :
We report on free space transmission experiments carried out on stacked split ring resonator (SRRs) arrays operating at microwaves. We start from the case of a single frequency selective surface which exhibits a rejection at the SRR resonance frequency. By stacking several SRR arrays in the propagation direction, we then show experimentally the possibility to induce a transmission band just below this resonance frequency. The results are interpreted by means of a full wave analysis which points out the role played by the magneto inductive waves in the electromagnetic properties of such 2D ½ metamaterials with the appearance of a transmission band resulting from a magnetic activity. Potential interest of this type of microstructures derives from the possibility of tailoring the dispersion characteristics of the stacked arrays.
