Hi Mike,
I didn’t see any responses to this .. I’ve been out for a while. The EMC Society (in its early years) did a *lot* of work on test sites for emissions. Basically they concluded that putting any sort of cover on the groundplane was not a good idea. Numerous papers were published and can be found on CDROM published by the EMC Society. To date I have not seen any publication to contradict that. Dan Heirman was (at least in my memory) at the forefront of this effort.
