Project files, *.PRO

The project files contain the general data defining a project as defined in the Project dialog. More specific data of a project are contained in the associated ASCII text files.

Data structure:

• File ID string (Current version: " CHPRO Version 3.1")

• Time-domain flag  (integer value 0: time, 1: frequency domain, e.g. 0)

• Complex frequency (2 real values, e.g. 1e9 0.0)

• Dimension Wave type (2 integer values 0:3D, 1:2D and 0: E, 1:H, 2: HE, e.g. 0 2)

• IF Dimension=2D: Complex (normalized) propagation constant gamma (2 real values, e.g. 1.5 0.0) Special case: when the second value is>1e300, the first one is z-per/2.

• Periodicity in X, Y, Z (3 integer values 0:not periodic 1: periodic, e.g. 0 0 0) Special case: first value -1: periodic in X but "regular 2D cell flag turned off.

• IF Periodic symmetry: Components of the lattice vectors Xx, Yx, Yy, Zx, Zy, Zz (6 real values, e.g. 1 0 1 0 0 1)

• Eigenvalue flag (1 integer value 0:scattering 1:eigenvalue problem, e.g. 1)

• IF eigenvalue problem: Eigenvalue search type, Save eigenvalue flag (2 integer values 0:Frequency search, 1:Gamma search, 2:CX search; 0:don't save, 1:Save on *.FUN file, 3: Save on *.FLD file; e.g. 1 0)

• IF eigenvalue problem: Search grid data (2 integer, 4 real values: nReal, nImag, Re(corner1), Im(corner1), Re(corner2), Im(corner2) e.g. 10 0 1.01 0.0 1.99 0.0)

• IF eigenvalue problem: Fine search data part 1(2 integer, 2 real values: eigenvalue number, max. iterations, eccuracy, flatness, e.g. 1 100 1.e-6 1e-6)

• IF eigenvalue problem: Fine search data part 2(4 real values: clip area - 2 complex corners, e.g. 0.0 1.0 0.0 0.1)

• XY, XZ, YZ symmetry numbers (3 integer values 0:no symmetry, 1:E tangential, 2:H tangential, e.g., 0 0 0)

• Number of digits for writing real numbers on files (1 integer value, e.g. 10)

• Blank line
