The viewer processes both the magnitude and angle of currents and displays them as static and dynamic plots. These plots provide insight and help you discover modifications for improved performance. Shown to the right is the current viewer plot of a meander line. Click here for a larger or animated view. This view shows the magnitude of currents along the meander line at one frequency.
Coupled lines have multiple propagation modes.
For example, two coupled lines have an even and odd propagation mode. There are N modes for N coupled lines. All EM simulators consider these modes. EM simulation is numerically expensive and execution is slower than circuit theory simulation. The MoL is well behaved numerically.
