Abstract
An optical element (transmissive or reflective) includes a transmissive layer comprising two different optical media arranged among discrete volumes arranged along the layer. The discrete volumes are arranged to approximate a desired phase function (typically modulo 2π) and are smaller than an operational wavelength in order to provide a range of phase delays needed to adequately approximate the desired phase function.
