Polarization-sensitive optical properties of an SSR.
(a), θinc-dependent σabs (black line) and σsca (red line). (b–d), Polar plots of the intensities of near-field electric field (b), far-field electric field (c) and power flow patterns at various θinc. The legend is for (b–d), indicating the values of θinc. The value of κ is −0.062 for all the plots. The angle of radiation (θrad) is defined in the right.
