# meow
> **M**odeling of **E**igenmodes and **O**verlaps in **W**aveguides
A simple electromagnetic [EigenMode Expansion (EME)](https://en.wikipedia.org/wiki/Eigenmode_expansion) tool for Python.
## Installation
### Minimal installation
```sh
pip install meow-sim[min]
```
### Full installation
```sh
pip install meow-sim[full]
```
### Selecting features
You can select which features to enable during installation as follows:
```sh
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-matrices
* `klu`: use `klujax` to speed up S-matric calculations (implies `jax`). 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 dependencies
* `full`: enable all the above features.

- [Tidy3D](https://github.com/flexcompute/tidy3d): meow uses the free FDE mode solver from Tidy3D.
- [SAX](https://github.com/flaport/sax): meow uses SAX as its circuit simulator when cascading the overlap S-matrices.
- [klujax](https://github.com/flaport/sax): Although technically an optional backend for SAX, klujax will significantly speed up the final S-matrix calculation of your structures.
- [EMEPy](https://github.com/BYUCamachoLab/emepy): an excellent alternative python-based EME solver with optional neural network mode solver.
