7.2 NTF

The NTF button in the Simulation tab invokes the Near To Far dialogue, which allows enabling and configuring the Near To Far postprocessing. In the NTF Frequencies field the frequencies at which radiation pattern of the structure should be calculated need to be set. The consecutive values should be separated by a coma.

In QuickWave the medium outside NTF box may be any isotropic dielectric. However, NTF Box will not automatically recognise the medium parameters that is why they must be explicitly given in the NTF background medium frame.

Detailed discussion concerning this postprocessing can be found in QW-Editor manual Section E 2.5.2.

Python code

The python code, which can be useful when creating project scripts, generated by Near To Far dialogue for default parameters:

App.ActiveDocument.QW_PostprocessingNTF.Active = True

App.ActiveDocument.QW_PostprocessingNTF.Frequencies = [5,10]

App.ActiveDocument.QW_PostprocessingNTF.Eps = 1.00000

App.ActiveDocument.QW_PostprocessingNTF.Mu = 1.00000

App.ActiveDocument.QW_PostprocessingNTF.Sigma = 0.00000

App.ActiveDocument.QW_PostprocessingNTF.SigmaM = 0.00000
