A fresh approach to the design of metamaterials formed from closely spaced helices is developed based on the retrieved values of electric and magnetic coupling coefficients between adjacent helices. A coupling retrieval method has been implemented to obtain numerical and experimental values for both electric-and magnetic-coupling coefficients between helical elements. Couplings between both right-and left-handed helices in side-by-side and axial arrangements are evaluated providing both positive and negative electric-, as well as magnetic-coupling components. The dependence of coupling strength on separation distance, relative axial rotation, helical pitch and the geometrical arrangement of the helices has been quantified both numerically and experimentally and a geometry giving zero net-coupling between very close helices is illustrated.

“…The dispersion of the MI waves is strongly affected by the coupling coefficient [7,8], which crucially depends on the relative orientation of the elements. The case of SRR elements has been fully studied in [9,10] and the influence of the operating frequency explored in [11].…”
