Simulating linear behavior of high Q silicon metasurface. a Schematic of silicon metasurface, d = 640 nm. b Circularly polarized transmission through metasurface with Δ = 0 (dashed gray curve) Δ = 10 nm (solid black curve). cf Electric field distributions, with colourmaps giving amplitude and vector directions given by arrows, in the x = y plane, shown in gray in a, for the four resonant modes in b. From the electric field vector maps, it can be seen that c and d are symmetric magnetic and electric dipoles, respectively, while e and f are anti-symmetric magnetic and electric dipoles, respectively. Scale bars are 250 nm. g On resonant electric field map at the z = 0 plane for mode f. Scale bar is 325 nm long. h E-field spin corresponding to the map in g. Scale bar is 325 nm long
