At the end of a planar MoM simulation, the current distribution nodes in the Navigation Tree become populated by the magnitude and phase plots of the three vectorial components of the electric ('''J''') and magnetic ('''M''') currents as well as the total electric and magnetic currents.

In order to view the near field distributions, you must first define field sensor observables before running the planar MoM simulation. To do that, right click on the '''Field Sensors''' item in the '''Observables''' section of the Navigation Tree and select '''Insert New Observable...'''. The Field Sensor Dialog opens up. At the top of the dialog and in the section titled '''Sensor Plane Location''', first you need to set the plane of near field calculation. In the dropdown box labeled '''Direction''', you have three options X, Y, and Z, representing the"normals" to the XY, YZ and ZX planes, respectively. The default direction is Z, i.e. XY plane parallel to the substrate layers. In the three boxes labeled '''Coordinates''', you set the coordinates of the center of the plane. Then, you specify the '''Size''' of the plane in project units, and finally set the '''Number of Samples''' along the two sides of the sensor plane. The larger the number of samples, the smoother the near field map will appear.
In the section titled Output Settings, Once you can also select close the field map type from two options: '''Confetti''' and '''Cone'''. The former produces an intensity plot for field amplitude and phaseField Sensor dialog, while the latter generates a 3D vector plot. In the confetti case, you have an option to check its name is added under the box labeled '''Data InterpolationField Sensors''', which creates a smooth and blended (digitally filtered) map. In the cone case, you can set the size node of the vector cones that represent the field directionNavigation Tree. At the end of a sweep planar MoM simulation, multiple the field map are produced and added to sensor nodes in the Navigation Tree. You can animate these maps. However, during become populated by the sweep only one field type is stored, either the E-field or H-field. You can choose the field type for multiple magnitude and phase plots using of the radio buttons in three vectorial components of the section titled electric ('''Field Display - Multiple PlotsE'''. The default choice is the E-) and magnetic ('''H''') fieldas well as the total electric and magnetic fields defined.
Once you close Note that unlike [[EM.Cube]]'s other computational modules, near field calculations in the Field Sensor dialog, its name [[Planar Module]] usually takes substantial time. This is added under due to the '''Field Sensors''' node of the Navigation Tree. At fact that at the end of a planar MoM simulation, the field sensor nodes in fields are not available anywhere (as opposed to the Navigation Tree become populated by the magnitude [[FDTD Module]]), and phase plots their computation requires integration of the three vectorial components of the electric (complex dyadic Green'''E''') and magnetic s functions (as opposed to [[MoM3D Module]]'s free space Green''H'''s functions) field as well as the total electric and magnetic fields defined in the following manner:.
