===2D Electrostatic Simulation Mode===
EM.Ferma's electrostatic simulation engine features a 2D solution mode where the 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 the project.
where η<sub>0</sub> = 120π Ω is the intrinsic impedance of the free space.
=== Setting up a Transmission Line Simulation ===
To perform a transmission line simulation, first draw your structure in the project workspace just like a typical 3D structure. Define a "Field Sensor" observable in the Navigation Tree so as to capture the cross section of your structure as your desired transmission line profile. Next, define a "2D Solution Plane" in the Navigation Tree based on your existing field sensor. When defining the 2D plane, check the box labeled "Perform 2D Quasi-Static Simulation". If an analysis is run with this option checked, the characteristic impedance Z<sub>0</sub>. and effective permittivity ε<sub>eff</sub> will be computed for the corresponding 2D Solution Plane.
Quasistatic analysis can only be performed with a Dirichlet boundary condition with 0V specified on the boundaries.
