HFSS15: Scaling a Source's Magnitude and Phase

You can scale the magnitude and set the phase of ports, voltage and current sources, Eigenmodes, and incident waves in the Edit post process sources dialog box. For HFSS modal projects, and HFSS-IE, you specify the total voltages. For HFSS terminal projects, you can also select either Incident Voltage or Total Voltage. The incident voltage selection includes magnitude, phase, and the impedance of a hypothetical external line. For HFSS Transient Network projects, the Edit Sources dialog includes tabs that let you specify scales for Spectral and Transient data separately. For HFSS Transient, Edit Sources is disabled.

For Driven Modal and Terminal Analysis solution types that involve near or far fields, a Source Contexts tab appears on the Edit post process sources dialog. This provides a means to select the sources to use as context when creating a radiated field report. The tab lists the same sources as the Spectral Fields tab. Sources are scaled by exciting a single source (the selected context in the reporter dialog) while turning off all other sources.

You can also Save to File and Load from File, where the file is comma delimited data (.csv) format or tab delimited data (.txt). This can help in defining source values for projects with a large number of sources. An example of the .csv format for HFSS follows:

Name,Magnitude,Phase

Port1:1,1W,0deg

Port2:1,0W,0deg

Port3:1,0W,0deg

An example of the tab delimited format follows:

Name Magnitude Phase

Port1:1 1W 0deg

Port2:1 0W 0deg

Port3:1 0W 0deg
