== Impedance /Dielectric Surface ==
ICON: [[File:voxel_group_icon.png]]
FUNCTION: Defines an impedance surface object group
TO DEFINE AN IMPEDANCE /DIELECTRIC SURFACE GROUP:
# Right-click on the '''Impedance /Dielectric Surfaces''' item in the navigation tree.# Select '''Insert New Impedance or dielectric Surface...''' to open up the impedance Surface dialog.
# Besides the color and texture properties, you have to enter values for the real and imaginary parts of '''Surface Impedance'''. The default values are 0 + j0 Ω, representing a PEC surface.
# Click the <b>OK</b> button of the dialog to return to the project workspace.

== Base Location Point Radiator Set ==
ICON: [[File:base_group_icon.png]]
# The only property of a base location set is its color, which you can change from this dialog.
# Click the <b>OK</b> button of the dialog to return to the project workspace.
# By default, the transmitter set is assumed to be made up of vertical half-wave radiators.
# You may also force the transmitters to adjust their Z-coordinates based on the underlying terrain surface.
# Click the '''OK''' button of the dialog to return to the project workspace. The new round symbols appear representing the transmitter set.
# You can open the property dialog of the transmitter set and change the radiator type to '''User Defined Antenna'''. In that case, click the '''Import Pattern''' button of the dialog to set the file path for a far-field radiation pattern data file of ".RAD" type. You can also additionally rotate the imported radiation pattern about its local X-, Y- and Z-axes.
# An imported radiation pattern file typically contains a total radiated power parameter at its file header. By default, this value is overridden and the '''Custom Power''' check box is checked. A default total power of 1W is assigned to each transmitter, which you can change to any arbitrary value. Or you may uncheck '''Custom Power''' to use the imported value of the total radiated power.
