A Faraday screen, shield, or cage is a network of parallel wires or
strips connected together at one end but disconnected from each other
at their opposite ends. I`ve worked at several broadcast stations which
used Faraday screens

The special comb-like structure that Richard describes, which is
deliberately constructed to block electric fields but transmit magnetic
fields, is normally called a Faraday "screen" - but not a cage.

The term Faraday "cage" is reserved for a complete conducting enclosure
that blocks both electric and magnetic fields from entering the
interior.

The rest of the discussion is about how well an incomplete or penetrated
enclosure might work as a Faraday cage.
