The EigenMode Expansion (EME) method is a frequency-domain technique useful for simulating very long waveguide-based structures. Its main advantage is that uniform sections of the structure require only a single cell for computation, while varying sections can be efficiently approximated using a limited number of cells. This approach can significantly reduce computational costs compared to FDTD method, while delivering highly comparable results.

Some common application examples include MMIs, tapers and couplers, and bent waveguides.
