===Defining a New Source===<table><tr>To create a new source, follow these steps<td> [[Image: * Right click on the name of the source type in the '''Sources''' section of the navigation tree and select '''Insert New SourceFDTD_FF4...''' from the contextual menu. This opens up the respective Source Dialog.* You can change the default name of the png|thumb|400px|A lumped source as well as its color.* Change the location of the source, if necessary, by the changing the values of the supplied coordinate fields. * Change the polarization of the source, if necessary. * In the '''Source Properties''' section, you can specify the '''Source Amplitude''' in Volts defined on a vertical PEC line object and the '''Phase''' in Degrees.* To change the amplitude and/or phase of a waveguide source, click the button labeled '''Excitation Waveform''' to open the Waveform Dialogdefined across a hollow PEC box.]] </td>* From the waveform dialog, you can also change the waveform type, if necessary<td> [[Image:FDTD_FF5. Once you define png|thumb|400px|A plane wave box enveloping a source, you can always changes its [[parametersPEC sphere.]] later from its property dialog, which can be accessed from its right-click contextual menu. You can also delete sources. </td></tr></table>
