吴国Assign Near Field Wave
This ction describes the Near Field Wave Options panel on the Incident Wave Source dialog box and how to assign near field waves. The following designs illustrate different ways of using near field sourcing to run a range of analys on a dish antenna fed by a circular horn antenna.
First we will bring up the Near Field Wave Options panel and then, assign Near Field Wave.
1. Click HFSS>Excitations>Assign>Incident Wave>Near Field Wave.
Note: If you are using HFSS-IE go to HFSS-IE>Excitations>Assign>Near Field Wave

The Incident Wave Source : General Data dialog box appears.
2. Fill in the Excitation name and click Next to acccess the Near Field Wave Options
panel.
Note: For array problems, the Active option includes the effects of the Near Field in
the simulation. To disable the effects, uncheck the Active option.
3. Determine whether you want to u a linked design or an external data file. If you are using a linked design go to step
4. If you are using an external data file, go to Access Near Field External Data File and follow the instructions.

4. Click the Setup Link button on the Incident Wave Source dialog to specify the linked design.
Note: It is through the Setup Link dialog box that you will link the source design to your target design.
5. On the Setup Link dialog box lect the radio button Edit Link.
The fields in the dialog box become active and editable as shown below.

6. Select the product in which you created your source design from the Product drop
down list.
谢谢你的爱早上跑步能减肥吗Note: Only HFSS, Maxwell, and SIWave appear in this list. An HFSS-IE project can be ud as target but not as source; so it is not listed.
7. Specify the project that has the source design in one of the following ways:
a. Check U This Project to pick a design from a current working project.
b. Click the ellipsis and brow your computer to pick the design.
Note The option The project directory of lected product points to the default
project directory location relative to the product that you lected from the drop-down menu. This is the same project directory that you t on the
General Options dialog under Tools>Options. This option is uful
especially, when you link across different products. The option This
project points to the directory relative to where your current working project is
史进located.
8. Pick the source design from the Source Design drop-down menu which lists all the designs in the specified project.
9. Pick the tup type from the Source Solution pull-down menu (e.g. Last Adaptive, or Sweep, etc.).
10. Select the last two checkboxes as needed and click OK .

This is the last option on the Setup Link dialog box. When the source design is clod or it is not included in the project manager window containing the target design, then the source design will not be saved. However, if you lect this option, which is especially when you are using Maxwell or SIWave the source design is saved.
11. Clo the Setup Link dialog , and if necessary, specify the Translation of Source Origin Relative to This Design on the Near Field Wave Options
panel of the

Incident Wave Source dialog box.
12. If required check the option Source Design is Fully Inside This Design .
When a source design is totally inside the target design, it should not be included into the near/far field calculation. If it is totally outside, the far field calculation should also integrate over the radiation surfaces of the source project.
13. If required check Include Source Power in Antenna Parameters .
The antenna parameters include power-related entries such as incident power,
accepted power, radiated power. If you check Include Source Power in Antenna Parameters the antenna parameters in the design that receives the fields from a source design will be bad on a power t for the excitations in the source design under HFSS>Fields >Edit Sources . For instance, this can be the power with which a port in a source antenna is excited. If the antenna in a source design is excited with 10 W, then the antenna parameters panel in the receiving design will show an incident power of 10 W.
14. Click Finish to clo the dialog. The Near Field wave source point and direction is highlighted in the modeler window, and the wave appears in the Excitations list in the Project
