Abstract:
An optical device, preferably for use in security devices and documents, comprising an arrangement of wavelength dependant optical phase, and optionally amplitude, modifying optical elements on a first surface of a substrate, each of the optical elements being in the form of an optical antenna and configured to produce a local phase change to reflected and/or transmitted electromagnetic waves, the arrangement configured such that the combined action of each of the optical elements produces a pre-defined optical effect on reflection and/or transmission observable by a viewer when the arrangement is illuminated by an external electromagnetic source.

Claim (Index 17):
A security document according to  claim 1 , wherein the optical elements are in the form of square or rectangular box shaped structures and each optical element has at least one predetermined length selected based on the local phase change required for the optical element.
