Directional Coupler Based on Metamaterial Square CSRR Shape

Z. Menachem, M. Haridim, S. Tapuchi, Y. Chattah


Metamaterials are artificial structures that can be designed to exhibit specific electromagnetic properties that are
not in the nature. In this paper, we design a directional coupler, based on the theory of the split-ring resonators
(SRRs), and the complementary SRR (CSRRs). The experiments and simulations of the directional coupler are
based on the theory of the square structure (and not based on the circular structure) of the SRR and CSRR. The
advantage of this circuit is that the area of the coupling is great as regards to the coupler based on the circular
structure. The results of simulation and measurement with the miniature structures show the backward-wave
phenomenon of the left-handed (LH) material.
