HFSS15: Radiation Boundary Panel

When assigning an incident wave either a radiation boundary, PML, or Finite Element Boundary Integral (FEBI) method must be defined at least on one section of the surface of the model. The Radiation Boundary panel is shown below. For the options in the Radiation Boundary panel to be active, at least one incident wave must be defined.

The options on the panel will impact the simulation as follows:

• For Radiation Only HFSS will use the scattered field formulation.

• For Incident Field HFSS will use total field formulation.

• For Enforced Field HFSS will use total field formulation enforcing the tangential component of the magnetic field to be equal to that of incident field.

• Model exterior as HFSS-IE domain is a FEBI method option.

• Reference for FSS can be used only if Master and Slave boundaries exist.

• Include for near/far field calculation can be checked if the source project resides outside the target project. This option is meant only for near or far field incident waves.

Note: If you select this option, it is your responsibility to ensure that the source project is located outside the target project. The location can be set on the Translation of Source Origin Relative to the Design sub-panel.
