yeah, even though they have a different job to do, RF anechoic chambers look surprisingly similar to acoustic anechoic chambers. a few jobs ago we had an RF anechoic chamber at our building; it was automotive-geared so the RF attenuation was taken care of by ferrite tiles places all over the walls and ceiling.
'cept those (4"x4") ferrite tiles were $15 each. And there were hundreds of them in that room.
