WebAug 20, 2009 · Intuitively, a helix under normal incidence of light acts somewhat similarly to an SRR under oblique incidence with respect to the direction normal to the SRR plane. However, extrinsic chirality (22, 23) observed for planar arrays of SRRs excited under oblique incidence also leads to additional linear birefringence (22, 24). Hence, in general ...
