Abstract

Ein Gitter (3) mit elektromagnetische Strahlung absorbierenden, zur Gitterbildung dienenden Kammelementen (12), wird zur Erhöhung der Robustheit und der Streustrahlenunterdrückungsqualität dadurch gebildet, dass Kammstege (11) quer zu einer zugehörigen, die Kammstege (11) tragenden Kammbasisfläche verlaufen.

Figure 00000001
A grid (3) with comb elements (12) which absorb electromagnetic radiation and serve to form a grid, is formed to increase the robustness and the stray radiation suppression quality in that comb webs (11) run transversely to an associated comb base surface carrying the comb webs (11).
