The Conceptual Problems of Ground-Planes

There are difficulties in trying to express the beliefs about ground-planes and grounding systems which are commonly held by practising EMC engineers in a form which is scientifically based, and so amenable to analysis. The impact of a conventional ground-plane on the compatibility of the inter-unit wiring of a large system is held to be adverse; some pointers are developed on how to use a ground-plane to make a positive contribution to EMC.
