Mode-matching / EME example for a straight rib-waveguide interface.
|
||||
|
||||
This example shows the intended user-facing workflow for `meanas.fdfd.eme` on a
|
||||
simple straight interface:
|
||||
|
||||
1. build two nearby waveguide cross-sections on a Yee grid,
|
||||
2. solve a small set of guided modes on each side,
|
||||
3. normalize those modes into E/H port fields,
|
||||
4. assemble the interface scattering matrix with `meanas.fdfd.eme.get_s(...)`,
|
||||
5. inspect the dominant modal coupling numerically and visually.
