3.2 1DC & 1DCL

In case of one dimensional gratings with a conical incident beam, 1DC gratings are used. If your script holds a set_delta(x) with 0 < x, and the grating is constructed as a 1D grating, you're working with a 1DC, and polarization setting is no longer needed

settings:

• set_alpha()
• set_delta()
• set_N()
• set_lambda()
• set_phi()
• set_psi()

Build a structure with Material, Slab 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 1DCL grating will be build, using the same settings and gettings as for a 1DC.
