Justification for the use of fragmented elements in the design of mosaic reflectarrays is provided whereby the far‐field pattern performance is shown to be good in spite of the optical mosaic image, and this fact is confirmed for an additional test case of a synthesised image. Additionally, the use of sub‐wavelength spaced elements, as opposed to the traditional half‐wavelength spaced elements, is strongly motivated by sampling density advantages for image reproduction.
