The above radiation pattern was computed using [[EM.Libera]], [[EM.Cube]]'s MoM3D computational module. The φ and θ components of the far-zone electric fields in the standard spherical coordinate system are stored in an ASCII data file with a ".RAD" file extension. With an original angular resolution of 1°, the data file contains a total of 361 × 181 = 65,341 rows containing the real and imaginary parts of the complex-valued E_θ and E_φ field components. This provides a fully polarimetric representation of the source's outgoing fields, which are then picked up and traced by [[EM.Terrano]]'s fully coherent and 3D-polarimetric SBR solver. Note that the complexity of the radiation pattern data file does not add any computational overhead to the SBR simulation. The figure below shows the received power coverage map of the Manhattan scene with an X-directed horizontal Yagi-Uda array. You can visibly see the directionality of the pattern of the transmitter from the coverage map in the area below the transmitter.
