Plot the coefficients as a function of the plane wave theta and phi
angles.

Tip: For (nearly) constant coefficients (such as in ϕ), use one θ cut to describe the
surface.

Note that the FSS elements have relatively good transmission through all θ and ϕ (> 0.7) at 10 GHz.
The plots also show that sufficient resolution (6°) was used to capture the variations in θ and ϕ.
