Re: [Smuthi] Far field pattern in example 3 of the tutorial

Hi Doan,

I think the confusion is because in Smuthi, angles are measured in radians.

So for ninety degree you need to provide 90 * np.pi / 180

Best regards, Amos

Dear all, 

I have hard time to understand the far field pattern of scattered field in example 3 of the tutorial. 

link:https://gitlab.com/AmosEgel/smuthi/-/blob/master/examples/tutorials/03_plotting_the_far_field/fifteen_spheres_on_substrate.py

When running with azimuthal_angle = 0, the pattern makes sense where maximum intensity at specular direction. However, when I changed to another angle (e.x azimuthal_angle = 90), the maximum is not at the specular direction anymore. I hope someone can educate me about this. Thank in advance.

Best, 

Doan
