HFSS15: Lumped Port: Post Processing

The parasitic inductance can be calibrated out of the s-parameter response with the deembed option for lumped ports. Click Next on the Lumped Port: Modes dialog box, to bring up the Lumped Port: Post Processing dialog.

Values here affect S-Parameters. They will also affect the spectral fields if you selected the Include Post Processing Effects on the Edit post process sources dialog box. By default, lumped ports are renormalized to a 50 Ohm full port impedance. You can override the default by entering a value of your choice in the Full Port Impedance field. If you want to enter a complex impedance, enter it in the form <re> + <im>j.

For a lumped port defined on a rectangular geometry HFSS provides an option to deembed the par

Note: For more information about the port calibration technique, see the topic When HFSS Needs Port Calibation (Deembedding).

The Deembed option can be turned on or off as a post processing operation without invalidating solutions. If multiple lumped ports are selected in the Excitations List panel, changes to the common Deembed property change the setting for all lumped ports at once, but only for those that support calibration.

If a port is selected for calibration but the validation checks fail for some variation (which could happen with a parametric solve), then the matrix data will not load for that variation. Also, if the fields are to include port post processing effects, then the fields do not load.
