In this letter it is presented a Left-Handed Metamaterial design route
based upon stacked arrays of screens made of complementary split rings
resonators under normal incidence in the microwave regime. Computation of the
dispersion diagram highlights the possibility to obtain backward waves provided
the longitudinal lattice is small enough. The experimental results are in good
agreement with the computed ones. The physics underlying the Left-Handed
behavior is found to rely on electroinductive waves, playing the mutual capacitive
coupling the major role to explain the phenomenon. Our route to Left-Handed
metamaterial introduced in this paper based on stacking CSRRs screens can be
scaled to millimeter and terahertz for future applications.
