Parameters (INTERNAL):

I1
PRE & FEK File
0
New excitation, replaces all previous excitations.
1
Additional excitation, add to previous excitations.
I2
PRE File
41
Read electric field values for a Cartesian boundary from a .efe file.
42
Read magnetic field values for a Cartesian boundary from a .hfe file.
45
Read both electric and magnetic field values for a Cartesian boundary from a .efe and .hfe file respectively.
FEK File
The type maps to ±9 that correspond to both electric and magnetic field values for a planar aperture that follow in the .pre input file.
I3
PRE File
Reference point (refers to a named point).
FEK File
Use the aperture definition from the file using the nth data block as specified by this number.
I4
PRE File
Direction of the U-vector (refers to a named point).
FEK File
The number of field points in the S1–S2 direction.
I5
PRE File
Direction of the V-vector (refers to a named point).
FEK File
The number of field points in the S1–S3 direction.
R1
PRE File
Use the aperture definition from the file using the nth data block as specified by this number.
FEK File
Scale the amplitude of the field values.
R2
PRE File
Describes where the reference point from I3 is located relative to the aperture box.
1
Base corner
2
Box centre
3
Face centre (U-min)
4
Face centre (U-max)
5
Face centre (V-min)
6
Face centre (V-max)
7
Face centre (N-min)
8
Face centre (N-max)
FEK File
Constant additional phase for the field strength (in degrees).
R3
FEK File
AP_S1_x (The x-value of S1).
R4
PRE File
Scale the amplitude of the field values.
FEK File
AP_S1_y (The y-value of S1).
R5
PRE File
Constant additional phase for the field strength (in degrees).
FEK File
AP_S1_z (The z-value of S1).
R6
PRE File
Super user option
0
Activate all default optimisations.
1
Do not use a spherical source representation for this AP card.
Swap source and field validity regions (since fek format 173)
2
Bitset option. This option is used for spherical, cylindrical or Cartesian boundary options to swap the source and field validity region. This option is not available for single Cartesian faces. By default, an aperture represents a source that is inside the aperture. The fields inside the box/sphere/cylinder are zero and the fields outside the box/sphere/cylinder are equivalent to the calculated or measured field values. When this option is selected, the aperture represents a source that is outside the aperture. The field contribution outside the box/sphere/cylinder is zero and the fields inside the box/sphere/cylinder are equivalent to the calculated or measured field values.
FEK File
AP_S2_x (The x-value of S2).
R7
FEK File
AP_S2_y (The y-value of S2).
R8
FEK File
AP_S2_z (The z-value of S2).
Filename
Path to file where the field values are stored.
Note: Filename(s) must be enclosed in double quotation marks.

If I2 = 41: Path to the .efe file.

If I2 = 42: Path to the .hfe file.

If I2 = 45: Path to the .efe file, followed by the path to the .hfe file.

2
Bitset option. The aperture represents a source that is outside the aperture.
R'1
AP_S3_x (The x-value of S3).
R'2
AP_S3_y (The y-value of S3).
R'3
AP_S3_z (The z-value of S3).
