3.3 2D & 2DL

Very easy: if you build a two dimensional grating, 2D is used, no matter what incident beam is used.

settings:

• set_alpha()
• set_delta()
• set_Nx()
• set_Ny()
• set_lambda()
• set_phi()
• set_psi()
• set_dzeta()

Build a structure with Material, Slab, Section and Stack.

gettings:

• diff_reff().R()
• diff_reff().T()
• field().R_TM()
• field().R_TE()
• field().T_TM()
• field().T_TE()

Now by changing the material refractive index from real into a complex, a 2DL grating will be build, using the same settings and gettings as for a 2D.
