First of all, if you use sources other than TFSF, you will capture a combination of incident and scattered waves, similar to what happens inside the Total-Field region of a TFSF source.
Second, the monitor should be positioned close enough to capture the full scattered field but far enough to avoid capturing evanescent (non-propagating) fields.
Best regards,
