Novel FDTD Huygens source enables highly complex simulation scenarios on ordinary PCs

This article demonstrated the effectiveness of a novel FDTD source called Huygens source. The source uses a generalized TFSF implementation and enables straightforward FDTD unidirectional subgridding with tremendous savings in CPU time and memory consumption. Furthermore, the incident field can be provided by other numerical EM tools like MoM and the new FDTD Huygens sources acts as a powerful hybridization between the two methods.
