Reply To: Do I need to use “farfieldfilter” in far field projections from a box of monitor

[Guilin Sun]

The farfield filter is used to smooth the fields in the monitor in order to not use very large simulation/monitor size. But the farfield accuracy might be compromised. 

If you are using box monitors, there is no need to use such filter, since it uses

farfieldexact

method to get the farfield from all related monitors.
