ZBFMULT

Multiplies the complex amplitude data in a ZBF file by a complex factor.

Syntax:

ZBFMULT filename, Ax, Bx, Ay, By
 

Discussion:

This keyword requires the name of the ZBF file to modify, and factors by which to multiply the real and imaginary components of the complex electric field for each point in the ZBF. The factors are applied to the x- and y-components of the electric field as follows, respectively, where E_x0 and E_y0 represent the original values in the ZBF.

E_x = E_x0(Ax + Bx*i)

E_y = E_y0(Ay + By*i)

The resulting data is written back to the same ZBF file name.

See "Purpose" for comments that apply to all ZBF related keywords.

Example:

ZBFMULT "some beam file name.ZBF", 0.0, 1.0, 0.0, -1.0
