Before inspecting the field profile, have you verified using the simulation output that the mode computed by MPB is correct (i.e., the frequency and wavevector match the band structure)? Also, the cross-sectional area that you are using to compute the fiber mode may not be sufficiently large t

[Meep-discuss] Fiber modes

2020-05-18 Thread SERAFINI VALENTINA
Good evening I am a beginner in Meep. I am currently trying to use Meep, with Python as programming Language, for calculate the scattering matrix of a piece of fiber. The geometry is described as two cilinder, one inside the other, whose refraction indices are 1.4482 for the core and 1.44 for
