Installation#
Minimal installation#
pip install meow-sim[min]
Full installation#
pip install meow-sim[full]
Selecting features#
You can select which features to enable during installation as follows:
pip install meow-sim[feature1,feature2,...]
Available features#
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
: useklujax
to 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.

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.
