HFSS15: Editing Sources for Spectral Fields for Transient Network
录入：edatop.com 点击：
For Spectral fields, you can optionally include port post-processing effects. The Spectral Fields tab on Edit post process sources controls Frequency domain far fields and antenna parameters. The voltage specifications are only for the incident voltage.
1. Click HFSS>Fields>Edit Sources.
The Edit post process sources dialog box appears with the Spectral Fields tab selected.
For HFSS Transient Network, the Edit post process sources dialog displays information for sources for Spectral Fields in table format. You can edit the Magnitude and Phase values including the use of variables, and set the units for each.. You can scale the sources individually through the source table in the Edit Sources dialog, or you can Save to File or Load From File, using the .csv format. This feature can help for projects with many sources. The steps below describe how to directly edit the source table.
Note | You may not enter a negative voltage. To obtain the equivalent of a negative magnitude, add or subtract 180 degrees from the phase value. If you use a design variable as a magnitude note that solutions are invalidated if the variable is changed. If the model contains symmetry planes, the Edit Sources dialog alerts you that you may need to adjust the scaling factor accordingly. At least one source should be excited (non-zero). If you set all sources to zero, you will receive a warning, but the values do go through. |
2. By option, you can click a checkbox to Include Post Processing Effects.
Checking this box also enables an Apply button.
3. For HFSS, if an incident wave is present, use the radio buttons at the bottom of the panel to select one of the following field types to use:
Scattered Fields | The differential field formed by subtracting the incident field from the total field. |
Total Fields | The physically measurable field that exists with the model present and a non-zero incident field. |
Incident Fields | The plane-wave field that would exist in the absence of the model. |
