Abstract
The behavior of cylindrical reflectors illuminated by complex linear arrays is simulated with the help of an infinite-array approach. Very large reflectors can be considered with a Method-of-Moments approach. The mutual coupling between elements can be obtained with the help of the array scanning method with non-regular sampling and FFT. A non-negligible variation versus frequency of the embedded element patterns and active impedances is observed. It results from array-reflector interaction and its period can be accurately predicted.
