Requesting Specific Absorption Rate (SAR)

Add a request to calculate the average absorption over a volume (volume-average SAR) or the maximum absorption in a 1 g or 10 g cube in a given volume (spatial-peak SAR).

  1. On the Request tab, in the Solution requests group, click the SAR icon.


    Figure 1. The Request SAR dialog.
  2. Under Select calculation, select the type of SAR calculation:
    • To calculate the average absorption over a volume, select Volume-average SAR.
    • To calculate the maximum absorption in a 1g cube in the model, select Spatial-peak SAR of a 1g cube.
    • To calculate the maximum absorption in a 10g cube in the model, select Spatial-peak SAR of a 10g cube.
  3. Specify the region where the SAR is calculated. Under Specify the search region, select one of the following:
    • To calculate SAR in all the dielectric regions in the model and calculate a single average or peak SAR value, select Entire model.
    • To calculate SAR in all media or a specified medium, select By medium.
    • To calculate SAR in a specific layer or in all the layers of a planar substrate, select In a planar substrate.
      Note:
      • Layer 0 is the upper free space region.
      • Layer 1 is the uppermost dielectric layer.
    • To calculate the 1g or 10g cube SAR at a specified location, select At a specified position. This option is not available for volume average SAR.
  4. In the Label field, add a unique label for the request.
  5. Click Create to request the SAR result and to close the dialog.
