EigenMode Expansion

Back to FIMMPROP

Bi-directional simulation of light propagation based on EigenMode Expansion (EME) is an innovative technique which allows you to model a very wide range of structures with a level of accuracy that methods such as FDTD or BPM cannot attain.

This short presentation is an introduction to EME, the method on which FIMMPROP is built. This introduction is not necessary to understand how FIMMPROP works but it will give you an insight into the underlying theory.
