SHG response versus incident angle, \(\alpha\), for four fixed light polarization directions s, sp, p, ps [left-hand panels (a–d)] and corresponding light polarization dependences of SHG response for three fixed incident angles \(\alpha\) (− 40\(^{\circ }\), 0\(^{\circ }\) and 40\(^{\circ }\)) [right-hand panels (a\(^{\prime }\)–d\(^{\prime }\))] measured in nanocomposite PS:BLZ membranes: PS (6.0 nm):BZL [(a) (a\(^{\prime }\))], PS (7.8 nm):BZL [(b) (b\(^{\prime }\))], PS (9.4 nm):BZL [(c) (c\(^{\prime }\))] and PS (13.0 nm):BZL [(d) (d\(^{\prime }\))]. The experimental error in the right-hand panels equals to the point size.
