<p>The installation (1) includes a basic surface of electrically conductive material, a groove (4) extending through the basic surface, which has an aperture at a first end for receipt and/or emission of electro-magnetic radiation. A feed device (8) converts electro-magnetic radiation present in the groove to an electrical signal or vice versa. In the basic surface (2,20,21) is a casing (5), into which the groove at its second end extends, for reflection of electro-magnetic radiation. The casing remains in contact via an aperture with an ambiance outside of the basic surface. The feed device has at least one electrically conductive component, extending into the casing near to the aperture. The feed device (6) is connectable with a signal processing unit for creation or supply of the electrical signal.</p> |
