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 parameters which have been modified for this example are the Initial frequency that is set to 10 GHz, which is the frequency of the simulation, and the Number of Bounces that is 10 bounces. As we are analyzing a cavity, it is recommended to consider multiple bounces.

The cylinder is a metallic structure. However, the ring is dielectric. Defining the new material named RAM60 as shown in Figures 6 and 7, it is added to the ring, Figure 8.

The far field observation directions considered are: cut in theta=90º and a sweep form phi=0º to phi=80º with 81 directions. It may be modified within the Output – Observation Directions menu.
