% create the dump boxes needed for the near field to far field transformation

% input:
|
|
% name: name of this nf2ff box
|
|
% start/stop: start/stop coordinates for the nf2ff box (this box has to
|
|
% enclose all radiating structures!)
|
|
% optional inputs:
|
|
% 'Directions': enable/disable specific directions, e.g.
|
|
% 'Directions',[1 1 0 0 1 1]
|
|
% -> disable nf2ff in +/-y direction
