Abstract
An optical element for introducing a predetermined phase delay into incident electromagnetic radiation. The optical element comprises a first layer and a second layer arranged in a propagation path of a portion of the electromagnetic radiation. The first layer comprises a transmission regions configured to introduce a first phase delay into the portion of electromagnetic radiation propagating therethrough. The second layer comprises a metasurface configured to introduce a second phase delay into the portion of electromagnetic radiation propagating therethrough. The metasurface comprises subwavelength sized structures.
