Complex radomes have long and costly development cycles, where simulation can significantly reduce such time and cost. newFASANT technology extends Altair Feko high frequency solution coverage for complex radomes, including FSS. A bit more in detail, this solution can accelerate modelling and simulation time by 50X for antenna and RCS problems. Radome modelling including FSS can be reduced from weeks to days, while MoM/MLFMM is parallelized with MPI/OpenMP, including optimization capabilities. This document contents 2 training examples. The first one is on parametric radomes and the second one on radomes with FSS.
