Hertzian-Dipole Wave
An incident Hertzian-Dipole wave can be specified as either an Electric dipole or a Magnetic dipole. The Electric dipole simulates the field of an elementary short dipole antenna placed at the origin. The Magnetic dipole is useful for EMC/EMI applications. Specify a Hertzian dipole as follows:
Cartesian Coordinates
- Click HFSS>Excitations>Assign>Incident
Wave>Hertzian-Dipole Wave.
- Select Cartesian
and click Next, the subsequent dialog
lets you define the dipole length.
- Define the types of dipole and the radius
in the Hertzian-Dipole Wave Options
dialog box.
The radius of Surrounding Sphere should be small enough so that a Hertzian dipole is placed into the computational domain when scattered field formulation is used. If you place a Hertzian dipole out of the computational domain, the Surrounding sphere can have any radius.
