Radome Design

Radome over horn

Radomes are generally electrically large structures, often consisting of more than one layer of dielectric that is spaced closely. The simulation of such structures stress computational resources greatly, making the choice of simulation method extremely important.

FEKO provides the following simulation techniques that were designed specifically for electrically large structures:

• Multilevel Fast Multipole Method (MLFMM), best suited to radomes with few dielectric layers.
  
• Method of Moments / Physical Optics (MoM/PO) hybridisation, best suited to low frequency simulations.
• Finite Element Method / Method of Moments (FEM/MoM) hybridisation, which is generally applicable within some geometric and frequency restrictions.
• Method of Moments / Geometric Optics (MoM/GO) hybridisation, combining detailed radiating element modelling with ray-launching technology for large complex dielectric structures.
