Abstract

Die Erfindung betrifft doppelbrechende Materialien und deren Herstellungsverfahren, wobei nachfolgende Schritte durchgeführt werden: Auswählen eines Materials, das für die vorbestimmte Lichtwellenlänge μ einen vorbestimmten Transmissionsgrad aufweist; Ätzen einer Vielzahl von Ausnehmungen (2) mit einer vorbestimmten räumlichen Orientierung, wobei die Ausnehmungen so orientiert sind, dass in parallelen Schnittebenen des Materials die Schnittflächen (3) der Ausnehmungen im wesentlichen eine gleiche Orientierung, eine charakteristische Länge L, eine charakteristische Dicke D, einen charakteristischen Abstand A zueinander aufweisen und nachfolgende Bedingungen erfüllt sind: L > D, L/D ≠ 1, μ/D > 10 für 100 nm < μ < 50000 nm, μ/A > 10 für 100 nm < μ < 50000 nm.
