Adding a Plane Wave Source

Add a plane wave source to illuminate a model with a uniform electric field.

Note: All sources are considered active during the calculation for each plane wave incident direction.
  1. On the Source/Load tab, in the Ideal source group, click the  Plane wave icon.

    Figure 1. The Add plane wave source dialog.
  2. In the Magnitude (V/m) field, specify the magnitude of the plane wave.
  3. In the Phase (degrees) field, specify the phase of the plane wave.
  4. Specify the operation mode using one of the following:
    • To create a single plane wave, click Single incident wave.
      Tip: Use multiple single incident plane wave sources to create a specific field distribution.
    • To create a single plane wave that loops over multiple directions, select Loop over multiple directions.
  5. In the Polarisation angle field, specify the angle, η in degrees, measured in a right-handed sense around the direction of propagation, from ϑ to E 0 .
  6. Under Polarisation, specify the polarisation type:
    • Left hand rotating elliptical
    • Linear
    • Right hand rotating elliptical
  7. [Optional] Select the Calculate orthogonal polarisations check box to create an additional orthogonal plane wave (although still a single plane wave source).
    Note: Select this option when exporting transmission / reflection coefficients to a .tr file.
  8. In the Ellipticity (0 to 1) field, specify the polarisation.
    • Ellipticity = 0: linear polarisation
    • Ellipticity 1: circular polarisation
  9. In the Label field, add a unique label for the plane wave source.
  10. Click the Create button to create the plane wave source and to close the dialog.
