If the project structure is excited by gap sources, and one or more ports have been defined, EM.Libera calculates the scattering (S) [[parameters]] of the selected ports, all based on the port impedances specified in the project's "Port Definition".
To calculate RCS, first you have to define an RCS observable instead of a radiation pattern. At the end of a PO simulation, the thee RCS plots σ<sub>θ</sub>, σ<sub>φ</sub>, and σ<sub>tot</sub> are added under the far field section of the navigation tree.
