Compact representation of the effects of mutual coupling in non-regular arrays devoted to the SKA telescope

This paper shows how an accurate, compact and fast representation of the embedded element patterns can be provided by the combination of spherical waves. Examples will be given for wideband non-regular arrays of bow-tie antennas containing up to 1000 elements, at the level of embedded-element and array patterns. It is expected that the provided representations will facilitate research on methods for array calibration for the SKA project.
