FEM Distributed Line Ports
The finite element method (FEM) distributed line port defines a Norton equivalent circuit port in a FEM region. The two terminals of the port are formed by two N-point polylines, defining the start and end points, respectively, of N discrete lines.
When a current source (I) is applied to the port, the current is divided uniformly between the N discrete lines of the port (discrete current values I/N).
When a load (Z) is applied to the port, the impedance is applied as parallel loads uniformly distributed over the N discrete lines (discrete load values ZxN).
Results: Circuit-based result quantities are calculated and returned for the port treated as a lumped element. The voltage across the port terminals is computed as the average of the voltages across the discrete lines.
