You can use [[EM.Ferma]] 's electrostatic simulation engine features a 2D solution mode where your physical model is treated as a longitudinally infinite structure in the direction normal to perform specified "2D Solution Plane". A 2D solution plane is defined based on a quasi-static analysis of multi-conductor transmission line structures, which usually provides good results at lower microwave frequencies (f < 10GHz)"Field Sensor" definition that already exists in your project.

[[EM.Ferma]]'s electrostatic simulation engine features a 2D solution mode where your physical model is treated as a longitudinally infinite structure in the direction normal to specified "2D Solution Plane". More than one 2D solution plane may be defined. In that case, multiple 2D solutions are obtained. A 2D solution plane is defined based on a "Field Sensor" definition that already exists in your project. To explore [[EM.Ferma]]'s 2D mode, right-click on '''2D Solution Planes''' in the "Computational Domain" section of the navigation tree and select '''2D Domain Settings...''' from the contextual menu. In the 2D Static Domain dialog, check the checkbox labeled "Treat Structure as Longitudinally Infinite across Each 2D Plane Specified Below". This would enable you to add new 2D Solution Plane definitions to the list or edit the existing ones. In the Add/Edit 2D Solution Plane dialog, you can choose a name other than the default name and select one of the available field sensor definitions in your project. At the end of a 2D electrostatic analysis, you can view the electric field and potential results on the respective field sensor planes. It is assumed that your structure is invariant along the direction normal to the 2D solution plane. Therefore, your computed field and potential profiles must be valid at all the planes perpendicular to the specified longitudinal direction.  <table><tr> <td> [[Image:Qsource14.png|thumb|left|750px|The 2D static domain dialog.]] </td></tr> </table> You can also use [[EM.Ferma]] to perform a quasi-static analysis of multi-conductor transmission line structures, which usually provides good results at lower microwave frequencies (f < 10GHz).
