The split ring resonator (SRR) is the key element to obtain left handedncss at microwave frequencies The orientation of the SRR relative to the electromagnetic field is decisive for achieving lefthandedness. We investigate by simulations how the lefthandedness is affected by rotational disorder of the SRRs in an array of 2 × 11 SRRs. Rotational disorder of the inner ring has a minor effect on the lefthandedness. Combined rotational disorder of inner and outer ring has a similar effect as rotational disorder of the outer ring only. Rotational disorder causes a shift in the frequency range of lefthandedness.
