=== Visualizing the Near Fields ===
In order EM.Picasso allows you to view visualize the near field distributions, you must first define fields at a specific field sensor observables before running the planar MoM simulationplane. To do Note that, right click on the '''Field Sensors''' item in the '''Observables''' section of the Navigation Tree and select '''Insert New Observable..unlike [[EM.Cube]]'''. The Field Sensor Dialog opens up. At the top of the dialog and in the section titled '''Sensor Plane Location'''s other computational modules, first you need to set the plane of near field calculationcalculations in EM. In the dropdown box labeled '''Direction''', you have three options X, Y, and Z, representing the"normals" to the XY, YZ and ZX planes, respectivelyPicasso usually takes a significant amount of time. The default direction This is Z, i.e. XY plane parallel due to the substrate layers. In fact that at the three boxes labeled '''Coordinates'''end of a planar MoM simulation, you set the coordinates of the center of the planefields are not available anywhere (as opposed to [[EM. Then, you specify the '''Size''' of the plane in project unitsTempo]]), and finally set the '''Number their computation requires integration of Samplescomplex dyadic Green''' along the two sides s functions of a multilayer background structure as opposed to the sensor plane. The larger the number of samples, the smoother the near field map will appearfree space Green's functions.
Once you close the Field Sensor dialog, its name is added under the '''Field Sensors''' node of the Navigation Tree{{Note|Keep in mind that since EM. At the end of Picasso uses a planar MoM simulationsolver, the calculated field sensor nodes in value at the Navigation Tree become populated by source point is infinite. As a result, the magnitude and phase plots of the three vectorial components of the electric field sensors must be placed at adequate distances ('''E'''at least one or few wavelengths) and magnetic ('''H''') field as well as away from the total electric and magnetic fields definedscatterers to produce acceptable results.}}
Note that unlike [[EMImage:Info_icon.Cubepng|40px]]Click here to learn more about '''s other computational modules, near field calculations in the [[Planar Module]] usually takes substantial time. This is due to the fact that at the end of Data_Visualization_and_Processing#The_Field_Sensor_Observable | Defining a planar MoM simulation, the fields are not available anywhere (as opposed to the [[FDTD ModuleField Sensor Observable]]), and their computation requires integration of complex dyadic Green's functions (as opposed to [[MoM3D Module]]'s free space Green's functions).
