8.6     Near To Near

The  button in Simulation tab and Postprocessings->NTN... command from main menu invoke Near To Near dialogue with settings for Near To Near post-processing.

Near To Far 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.

NTN background 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 NTN background 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.

Using NTN processing user can define set of NTN Points cloud which can be arbitrary shaped in arbitrary location in space. In each point EM field will be calculated in chosen set of frequencies.
