Format
$SourceType 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 , 0° ≤ ψ < 360°. (polarization angle)
