Setting up an RCS Sweep Configuration

Set up an RCS sweep configuration. The farm_rcs_to_cluster.lua uses the frequency and incident angle information from plane wave sources in the model to create the sweep.

  1. Tip: Find the examples in the <FEKO_SHARED_HOME> directory:


    Open RCS_base.cfx in CADFEKO.
    The RCS_base.cfx model is displayed.

    Figure 1. The RCS_base.cfx model.
  2. In the model tree (Configuration tab), view the frequency options for StandardConfiguration1.
    The Solution frequency dialog is displayed.

    Figure 2. The Solution frequency dialog.

Note: If the frequency is defined globally, the same sweep setup is used for all the configurations when creating the individual models.

  1. On the Frequency tab, from the drop-down list, select how the frequency is swept:
    • Select Single frequency, if only one frequency point is required.
    • Select Linearly spaced discrete points, for a linear sweep between the start and end frequency points.
    • Select Logarithmically spaced discrete points, for a logarithmically spaced frequency sweep.
    • Select List of discrete points, for a specific set of frequency points for the sweep.
  2. Enter the required frequency parameters.
  3. Modify the plane wave source in the model.
    • Select Single incident, if only one angle of incidence is required.
    • Select Loop over multiple directions, if multiple angles of incidence are required in the sweep.

  4. Enter the Start, End and Increment for each angle of interest.
  5. [Optional] Specify the Polarisation angle or select Calculate both orthogonal polarisations check box.
  6. [Optional] Multiple plane wave sources can be added per configuration if different blocks of incident angles are required for a sweep.
    Two plane wave sources are shown each using a specific angle of incidents for the sweep configuration.

    Figure 3. An example of a sweep setup using multiple plane wave sources.
  7. Add requests as required, for example, far fields, near fields and currents.
  8. [Optional] Add additional configurations, if multiple sweeps for different frequencies and angle if incidents are required. Follow Step 2 to Step 8 for each sweep configuration.
    An additional sweep configuration is added to the model.
    Note: For each sweep configuration a subfolder is created in the output folder for the individual models with the configuration name as label.
