The main simulation parameters are resumed in this section, such as the information about the units, materials and observation directions.
Click on Simulation – Parameters to open the Simulation panel. The only parameter which has been modified for this example is the Initial frequency that is set to 3 GHz, which is the frequency of the simulation for the dihedral and trihedron case and 9GHz for the cavity cases. The number of bounces will be changed, double effects will be considered in the dihedral case, triple effects will be considered in the trihedron case and until 10 bounces will be considered in the cavity case.
Figure 10: Simulation parameters for the dihedral case.
As the dihedral is a metallic structure, no materials are required for this example.
The monostatic RCS will be computed as shown in Figure 11.

The far field observation directions considered are: cut in phi=0º and a sweep from theta=0º to theta=90º with 91 directions for the dihedral and the trihedron case. For the cavity case, a sweep from theta=0º to theta=180º with 37 directions has been considered. It may be modified within the Output – Observation Directions menu.
