Abstract
A window assembly includes a transparent window layer and a first coded mask layer provided on a first surface of the window layer, the first coded mask layer having a first shape configured to change a first property of light passing through the window assembly. The first coded mask layer may include a meta-surface including a phase modulation meta-pattern. The meta-surface may further include an amplitude modulation meta-pattern. A second coded mask layer having a second shape configured to change a second property of the light passing through the window assembly may further be provided on a second surface of the window layer.
