Fields Post Processing in HFSS 3D Layout

To analyze the radiated fields associated with a design, define a radiation surface over which the fields are calculated. Such a surface can be a boundary radiation surface, or a custom radiation surface that you define as an object face.

To plot near fields on a plane in HFSS 3D Layout:

1. First define a near field setup. From the Project Tree, right-click Radiation and select Insert Near Field Setup > Plane
2. From the Near Field Plane Setup window that opens, click OK. A new Plane setup appears in the Project Tree.
3. From the Project Tree, right-click Results and select Create Near Fields Report, then select Rectangular Contour Plot or Data Table.
4. From the Report window that opens, select "PlanarEM Setup" in the Solution menu and select a Plane setup in the Geometry menu. Enter "x" for the Primary Sweep and "y" for the Secondary Sweep, then click New Report. The plot appears and a new Radiation setup with the name of the selected Plane is created in the Project Tree.
