 type    axis    dir    θ    φ    ψ            // type, axis, and dir are integers, the others are floating.

 type: 1~4 dual wave: sin, exp, sin*exp, multi-sine; 
       11~14 one dir.: sin, exp, sin*exp, multi-sine;
       21~24 TF/SF
       31~34 cuboid source (not finished)
       51~54 point source (hard source)
       61~64 point source (soft source)

 axis: 1~3 represents the source is along x, y, or z axis.

 p.s.1 it is useless for TF/SF source.
 p.s.2 for point source, axis means the direction of dipole.

 dir: -1 means the wave goes to negative, 
       1 means the wave goes to positive.

 p.s. it is useless for TF/SF and point source.

 θ, φ, ψ: the unit is degree and will be changed to radian in the program.
          θ is relative to the +z-axis of the space lattice, 0° ≤ θ <180°.
          φ is relative to the +x-axis of the lattice, 0° ≤ φ < 360°.
          ψ is relative to the direction  $\hat{\mathbf{k}}_{inc} \times \hat{\mathbf{z}}$ , 0° ≤ ψ < 360°. (polarization angle)
