Fig. 13.17 a Transmission spectra of randomly arranged identically oriented rectangular apertures
with dimensions of 80 × 220 nm in 86 µm square array, and of a homogeneous chain with period
Φ = 430 nm, local orientation τ = 45 ∈ and a length of 86 µm. The red and blue lines/arrows
correspond to linear polarization excitations parallel and perpendicular to the nanorod’s minor axis,
respectively. The insets show SEM images of the structures described above. b SEM image of a
chain in which the nanorods’ orientation τ varies linearly along the x-axis with a rotation period
of a = 3.44 µm, and a structure length of 86 µm. c The spin-dependent momentum deviation for
the OSHE-LA, at a wavelength of 730 nm. The red and blue lines stand for incident spin states
λ in = ±1, respectively. Reprinted with permission from Ref. [35]. Copyright 2011 American
