7.4 NTN
The NTN button 
in the Simulation tab and Postprocessings->NTN... command from main menu invoke Near To Near dialogue with settings for Near To Near post-processing.
Near To Near post-processing performs the near field to near field transformation in the frequency domain.
When choosing Frequency band option we must decide upon the range of frequencies we are interested in, and define the frequency step determining the frequency points at which the near-to-far field transformation will be performed.
Background medium shows current settings of the surrounding medium parameters (permittivity, permeability, conductivity and magnetic loss), which will be used by the Near To Near calculations. Parameters of the Background medium must be the same as respective entries seen for the surrounding medium in Project Media dialogue. QuickWave does not check the consistency between the settings made here, and those in Project Media dialogue. Inconsistent settings will lead to physically inconsistent postprocessing results.
The Near To Near results can be observed in Fields window in QW-Simulator.
Python code
The python code, which can be useful when creating project scripts, generated by Near To Near dialogue without Frequency band option:
App.ActiveDocument.QW_PostprocessingNTN.Active = True
App.ActiveDocument.QW_PostprocessingNTN.AllowBand = False
App.ActiveDocument.QW_PostprocessingNTN.Frequencies = [5,10]
App.ActiveDocument.QW_PostprocessingNTN.Eps = 1.00000
App.ActiveDocument.QW_PostprocessingNTN.Mu = 1.00000
App.ActiveDocument.QW_PostprocessingNTN.Sigma = 0.00000
App.ActiveDocument.QW_PostprocessingNTN.SigmaM = 0.00000
