FEEM

FEEM provides superior accuracy and performance scaling with a finite element Maxwell’s solver based on the Eigenmode method. A material-adaptive finite element mesh and the use of higher-order polynomial basis functions make FEEM well suited for highly accurate analysis of waveguide modes in complex geometries and materials.
