Huygens Box
Generalized Huygens box hybridization platform for importing EM near-field patterns, calculated by different numerical methods (FDTD, FEM, MoM), into the generalized Huygens source.
 |
Features
- Effectively couples different solvers without accelerating error propagation
- Generalized total-field scattered-field (TFSF) plane wave excitation and the block iterative technique for problems of weak coupling
- Interfaces to other method-of-moments (MoM) and FEM simulation packages (e.g., FEKO, Wipl-D)
- Cascaded simulation with 3D field excitation and grid refinement
