Abstract :
The distribution of induced currents across three surfaces each containing approximately 100 linear dipoles has been computed. The illuminating field on groups of elements at the array edges is set to zero. Element coupling is frequency dependent, and in the surface reflection bands the current amplitudes can decay relatively slowly with distance from the illuminated sectors
