b_split - splits one beam into two beams.
b_split and b_mix are two commands useful to model interferometers. With b_split we split the field structure (amplitude division) to two field. b_split provides the possibility of amplitude division, preserving the sum of intensities of the two splitted beams. The two obtained files could be processed separately and then mixed again with b_mix .
