ABSTRACT:
Chiral composite material is made using an apertured plate (2) having apertures (3) therethrough corresponding to the desired locations of chiral elements (4) in the composite material. The plate (2) is located to overlie a substrate (1) with or without the intermission of spacer (10) which may be apertured in correspondence with the plate (2) or which may be ring like in form. The chiral elements (4) are held in position by locating means such as a tab (5) which may be magnetic in, on or associated with the plate (2) and a first layer (8) of liquid host material is placed in the apertures (3) around the elements (4) against the substrate (1), allowed to set and the plate (2) removed. A second layer (9) of liquid host material is then applied to the set first layer (8) and allowed to set to produce the desired composite material.
