Shielding Effectiveness#

The Shielding Effectiveness extension computes the shielding effectiveness of an enclosure. It calculates the attenuation of an electromagnetic field inside the enclosure due to the presence of a shield.

The extension provides a graphical user interface (GUI) for configuration, or it can be used in batch mode via command line arguments.

The following image shows the extension GUI:

Features#

  • Configure input parameters including source sphere radius, polarization, start and stop frequency and dipole type.

  • Automatic HFSS setup.

  • Switch between light and dark themes in the GUI.

Using the extension#

  1. Open the Automation tab in the HFSS interface.

  2. Locate and click the Shielding Effectiveness icon under the Extension Manager.

  3. In the GUI, users can interact with the following elements: - Source sphere radius: Source sphere radius in meters. It must fit inside the shielding. - Polarization: X, Y, Z polarization component. - Frequency: Start and stop frequency and the number of steps to analyze. - Electric dipole: Activate electric dipole. Electric or magnetic dipole are available. - Cores: Number of cores for the simulation. - Toggle between light and dark themes.

  4. Click on Launch to start the automated workflow.

Command line#

The extension can also be used directly via the command line for batch processing.

Use the following syntax to run the extension:
