Incident Cylindrical Wave
An incident Cylindrical wave is a wave that simulates the far field of an infinite line current placed at the origin.
- Click HFSS>Excitations>Assign>Incident Wave>Cylindrical Wave.
- Select the Vector Input Format as Cartesian coordinates.
- Enter the X-, Y-, and Z-coordinates of the Excitation Location and/or Zero Phase Position (the origin for the incident wave).
- Click Next.
- If you selected Cartesian, the Incident Wave Source: Cartesian Vector Setup page appears. Enter the X-, Y-, and Z-components for the I Vector in the X, Y, and Z boxes. I is the current amplitude (peak value). Units are Amps (A).
A single incident wave will be defined.
Note:
Only a single incident wave angle can be defined for periodic structures which are defined with primary and secondary (Lattice pair) boundaries
- Click Next. the Incident Wave Source: Cylindrical Wave Options page appears.
- Select the Radius of Surrounding Cylinder. Inside this cylinder, the field magnitude will be made equal to the field magnitude calculated on the surface of the cylinder. To restore the default (10 mm), click Use Defaults.
- Click Finish.The incident wave you defined is added to the Excitations list in the Project.
