Frequency dependent loss tangent and permittivity

questex17.in : Frequency dependent loss tangent and permittivity

Requires: QUEST

This example is based on Questex04.

To load and run this example, select the Load example button in DeckBuild. This will copy the input file, GDSII file and results to your current working directory. Select the run button to execute the example.

The GDSII file can be viewed in MaskViews, Expert or any other layout editing tool that can read GDSII format.

You can compare the results of the inductor parameter (Q factor) according to the substrate properties and permittivities. The files questex17_losstangent.txt and questex17_permittivity.txt, where losstangent and permittivity are defined versus frequency, are loaded using the parameters permit.file and loss.file in the material statement. The frequency range used during QUEST simulation should match the frequency used to define questex17_losstangent.txt and questex17_permittivity.txt files. For that, use the list parameter on the frequency statement.

A two port simulation is defined by using the reserved electrode name called "subs_ground". This grounds out the reference electrode for both the "in" port and the "out" port of the two port network.

All the results will be placed in a directory structure under the name "questex17_db" which was defined with SAVE command.

Three dimensional structure files can be viewed with TonyPlot3d. All other RLCG and Q versus frequency data can be viewed with TonyPlot.
