Define Near Field from Data
Apply an array of electric and magnetic dipoles in the model (in the form of a planar aperture) that is equivalent to measured or calculated field values.
- Source Files
- The user can import the E-Field and H-Field files by pressing the
Browse button and selecting the text files in
their hard drive. These files contain the electric and magnetic field
for every point in the U and V direction, four columns for the E-Field
file with EU (Amplitude V/m), EU (Phase deg),
EV (Amplitude V/m), EV (Phase deg); and four
columns for the H-Field file with HU (Amplitude V/m),
HU (Phase deg), HV (Amplitude V/m),
HV (Phase deg) (see Figure 2).
- Start reading from line number: Skip this number of lines before reading the field values.
- Cartesian Coordinate System: Allows the
user to define the planar aperture, the E-Field and H-Field
files must contain a field value for each point defined in this
section.
- Width (W): Array size in U direction.
- Height (H): Array size in V direction.
- Number of points (U): The number of points in U direction.
- Number of points (V): The number of points in V direction.
- Displacement: This parameter is a vector that specifies the translation applied to the points when added to the simulation.
- Orientation: This parameter allows the rotation applied to the points. There are several ways the user can specify this rotation: by giving each of the axis directions of the transformation, by specifying spherical rotation angles, by specifying rotation angles on each axis or by specifying the Z axis and a rotation angle.
If the Relative to reference plane check box is selected, the displacement and rotation will be relative to the current reference plane coordinate system.
