=== EM.Libera's Output Simulation Data ===
At the end of a 3D MoM simualtion, EM.Libera generates a number of output data files that contain all the computed simulation data. The primary solution of the Wire MoM simulation engine consists of the linear electric currents on the wires and wireframe structures. The primary solution of the Surface MoM simulation engine consists of the electric and magnetic surface currents on the PEC and dielectric objects. EM.Libera currently offers the following types of observables (click on each type to learn more about it):
* '''[[Data_Visualization_and_Processing#Visualizing_3D_Current_Distribution_Maps | Current Distributions]]''': Electric and magnetic surface current amplitude and phase on all metal and dielectric surfaces and electric current amplitude and phase on all wires * '''[[Data_Visualization_and_Processing#The_Field_Sensor_Observable | Near-Field Distributions]]''': Electric and magnetic field amplitude and phase on specified planes and their central axes* '''[[Data_Visualization_and_Processing#Computing_and_Graphing_Port_Characteristics | Port Characteristics]]''': S, Z and Y [[Parameters]] and Voltage Standing Wave Ratio (VSWR)
* '''Radiation Characteristics''': Radiation Patterns, Directivity, Total Radiated Power, Axial Ratio, Main Beam Theta and Phi, Radiation Efficiency, Half Power Beam Width (HPBW), Maximum Side Lobe Level (SLL), First Null Level (FNL), Front-to-Back Ratio (FBR), etc.
* '''Scattering CharacteristicsRadar Cross Section (RCS)''': Bi-static and Mono-static Radar Cross Section (RCS)
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".
