Online AR-filter analysis
Activates the online AR-filter analysis. The
Auto Regressive (AR)-filter is a signal-processing method to predict time
signals to save simulation time. These predicted signals are then used
to calculate the scattering matrices. Using AR-filtering is reasonable
when simulating very resonant structures.
Maximal energy dev. for steady state
The maximal energy deviation is the desired
value for the accuracy of the scattering parameter approximation achieved
by the AR-filter. For real loss-free structures, the energy balance should
be 1 over the whole frequency range. Every deviation is directly related
to the error made by the calculation.
Pulse widths between checks
Set the number of pulses between the AR-filter
computations.
