CalcNF2FF

CalcNF2FF(nf2ff, Sim_Path, freq, theta, phi, varargin)

Full definition:

function nf2ff = CalcNF2FF(nf2ff, Sim_Path, freq, theta, phi, varargin)

Calculate the near-field to far-field transformation created by CreateNF2FFBox

IMPORTANT: Make sure to define the correct nf2ff phase center, aka. central antenna position! See optional parameter below!! Default is [0 0 0]

parameter:

  • nf2ff: data structure created by CreateNF2FFBox

  • Sim_Path: path to simulation data

  • freq: array of frequencies to analyse

  • theta,phi: spherical coordinates to evaluate the far-field on (in radians)

optional parameter:

  • ‘Center’: nf2ff phase center, default is [0 0 0] !! Make sure the center is never outside of your nf2ff box!! Definition is the correct coordinate system necessary –> either Cartesian or cylindrical coordinates

  • ‘Mode’: ‘Mode’, 0 -> read only, if data already exist (default) ‘Mode’, 1 -> calculate anyway, overwrite existing ‘Mode’, 2 -> read only, fail if not existing

  • ‘Outfile’: alternative nf2ff result hdf5 file name default is: <nf2ff.name>.h5

  • ‘Verbose’: set verbose level for the nf2ff calculation 0-2 supported

  • ‘Radius’: specify the radius for the nf2ff

  • ‘Eps_r’: specify the relative electric permittivity for the nf2ff

  • ‘Mue_r’: specify the relative magnetic permeability for the nf2ff

  • ‘Mirror’: Add mirroring in a given direction (dir), with a given mirror type (PEC or PMC) and a mirror position in the given direction. Example: ‘Mirror’, {0, ‘PMC’, +100}
