Polyomino-Shaped Subarrays for Time Delay Control of Planar Arrays

This paper describes a practical technique for using polyomino-shaped subarrays. A polyomino is a geometric figure made up of N square areas assembled into a given shape. The subarrays are used to completely "tile" the aperture, which means that they completely fill the aperture without any gaps or holes. In this study we use contiguous polyomino-shaped subarrays that are identical, but irregular instead of rectangular, and are assembled into apertures by rotating or rotating and flipping (overturning) each subarray
