From: Diffractive properties of imaginary-part photonic crystal slab
Dependence of four first-order diffractions on incident angle and polarization. Four first-order diffractions (0,1), (0,−1), (1,0), and (−1,0)with TM and TE incident light on incident angle. (a) and (b) show the FODE atλ0with incident light in the Γ−Xdirection with different θ, while (c) and (d) show it with different ϕat θ=60°.
