# API Overview

The package is documented directly from its docstrings. The most useful entry points are:

- meanas: top-level package overview
- eigensolvers: generic eigenvalue utilities used by the mode solvers
- fdfd: frequency-domain operators, sources, PML, solvers, and far-field transforms
- waveguides: straight, cylindrical, and 3D waveguide mode helpers
- fdtd: timestepping, CPML, energy/flux helpers, and phasor extraction
- fdmath: shared discrete operators, vectorization helpers, and derivation background

The waveguide and FDTD pages are the best places to start if you want the mathematical derivations rather than just the callable reference.
