Figure 2: Radiation pattern of (Upper Left) a vertical short dipole above a PEC ground, (Upper Right) a vertical short dipole above a PMC ground, (Lower Left) a horizontal short dipole above a PEC ground, and (Lower Right) a horizontal short dipole above a PMC ground. The bottom (-Z) boundary is set to PEC or PMC, even though it is not visible.
===Radar Cross Section===
When the physical structure is illuminated by a plane wave source, the calculated far field data indeed represent the scattered fields. In that case, the incident and scattered fields can be separated. EM.Cube can calculate the radar cross section (RCS) of a target defined as:
