Modeling of Eigenmodes and Overlaps in Waveguides
A simple electromagnetic EigenMode Expansion (EME) tool for Python.
pip install meow-sim[min]pip install meow-sim[full]You can select which features to enable during installation as follows:
pip install meow-sim[feature1,feature2,...]min: minimal installation (equivalent to not specifying any features)vis: explicitly installs matplotlib and trimesh.jax: use JAX in stead of numpy to calculate the S-matricesklu: useklujaxto speed up S-matric calculations (impliesjax). Note: you need the SuiteSparse headers on your computer for this to work.gds: enable GDS creation with GDSFactory (see GDS Taper example).ipy: install useful jupyter/ipython packages.dev: install dev dependenciesfull: enable all the above features.

- @jan-david-black: fixing mode overlaps and more
- DALL-E: “a drawing of a kitten with laser eyes walking towards me” (logo)
- Tidy3D: meow uses the free FDE mode solver from Tidy3D.
- SAX: meow uses SAX as its circuit simulator when cascading the overlap S-matrices.
- klujax: Although technically an optional backend for SAX, klujax will significantly speed up the final S-matrix calculation of your structures.
- EMEPy: an excellent alternative python-based EME solver with optional neural network mode solver.
