Abstract

L’invention concerne un ensemble de véhicule (1) comprenant un capteur (10) pour émettre des ondes (R1) dans une plage (Δ1) de longueurs d’onde, et un agencement de couches (11) comprenant une couche primaire (111) avec un indice de réfraction primaire (n1) comprenant une surface d’entrée (S1) des ondes (R1) et présentant un relief (1110) sur une surface opposée (S1’) à la surface d’entrée (S1), et une couche secondaire (112) avec un indice de réfraction secondaire (n2), adjacente à ladite couche primaire (111) et comprenant une surface de sortie (S2) des ondes (R1), caractérisé en ce que ladite couche primaire (111) comprend des particules de matière (114) d’indice de réfraction (nm) différent de l’indice de réfraction primaire (n1), et l’indice de réfraction secondaire (n2) est sensiblement égal dans la plage (Δ1) de longueurs d’onde à un indice de réfraction équivalent de la couche primaire (111) avec les particules de matière (114).
