<p>An energy absorbing arrangement suitable for use in anechoic chambers comprises an assembly of elongate planar strips arranged in two sets of parallel strips in a crossing relationship. The strips carry energy absorbing material and in one preferred embodiment consist of cardboard coated with carbon black. The assembly may be easily manufactured as a large number of strips may be produced in one cutting step. Inexpensive material may also be used and by using an arrangement of this type complex impedance profiles may be produced.</p> |
