We are looking for a method to extract the power of electric field from the CST Microwave studio simulation.
Thanks
You can plot energy density directly using a monitor. The square of E or the square of H are not power. They are proportional to energy density. Power density is a different monitor. You may be able to write a macro to export them.
This site has the macro below, which you may be able to adapt, if it works!

Re: export E and H fields from CST as *.txt files
Consider you have 101 frequency monitors and you have named those monitors 'Freq=0.5e9', 'Freq=2e9' etc. Then you can use macro to select the results for each monitor in the loop and export the data. See sample below: ================================================== == Sub Main () For ii=0.5e9 To 2e9 STEP 0.015e9 SelectTreeItem ("2D/3D Results\E-Field\e-field Freq="&ii&"") With ASCIIExport .Reset .FileName (".\E_FIELD_FREQ_"&ii&".dat") .StepX (0.1) .StepY (0.1) .StepZ (0.1) .Mode ("FixedWidth") .Execute End With SelectTreeItem ("2D/3D Results\H-Field\h-field Freq="&ii&"") With ASCIIExport .Reset .FileName (".\H_FIELD_FREQ_"&ii&".dat") .StepX (0.1) .StepY (0.1) .StepZ (0.1) .Mode ("FixedWidth") .Execute End With Next End Sub ========================================= You might need to adjust the macro to the naming style you use for your field monitors.
