Thin Wire Source

The EMA3D thin wire source tool allows users to create a thin wire to serve as an excitation source.

Instructions
  1. ClickAntenna Image 16 Thin Wire within the Excitations section under the EMA3D tab in the ribbon.

  2. antenna 1
  3. In the Properties Panel, adjust the thin wire source properties as desired.

  7. Drag the cursor to use the select point tool to select the point to which to assign the thin wire source location. It will be immediately recolored yellow. If you selected a Pin Injection Voltage source, the excitation point will automatically jump to the closest end point of the thin wire to where the user clicked.

Meaning

Source Geometry

  • Inline - Voltage source is applied within the thin wire geometry

  • Pin Injection - Voltage source is applied at one end of the thin wire

In Series

  • True (Blue lettering) - Place the voltage source pin injection in series with the termination boundary condition

  • False (White lettering; default) - Overwrite the termination boundary condition at the pin injection location
