== Filamentary Current Source ==
ICON: [[File:hertz_src_icon.png]]
MODULE: [[EM.Tempo]]
FUNCTION: Places a filamentary current source at a specified location in the project workspace
TO DEFINE A FILAMENTARY CURRENT SOURCE:
# Right-click on the '''Filamentary Current Sources''' item in the navigation tree.
# Either select '''Insert New Hertzian Short Dipole Source...''' or select '''Insert New Long Wire Current Source...''' to open up the Filamentary Current Source Dialog.
# By default, the filamentary current source is placed at the origin of coordinates. You can modify the source's center coordinates.
# The "Current Distribution Profile" dropdown list provides four options: Hertzian Short Dipole Radiator, Uniform Long Wire Current, Triangular Long Wire Current and Sinusoidal Long Wire Current. Select the desired type.
# By default, a vertical Z-directed current is defined. You can change the components of the unit vector along the dipole to reorient it along any arbitrary direction. In the case of a long wire current source, it has to be oriented along one of the three principal axes. In other words, only one of uX, uY or uZ components must be one and the other two must be zero.
# You may also modify the current amplitude and phase as well as the filament length.
# Click the '''OK''' button of the dialog to return to the project workspace.
NOTES, SPECIAL CASES OR EXCEPTIONS: A filamentary current source with Hertzian short dipole radiator profile is equivalent to [[#Hertzian_Short_Dipole_Source | Hertzian Short Dipole Source]] in the other computational modules of [[EM.Cube]].
