Array Realizations of Complex-Source Beams
Abstract
The inverse source problem for the complex-source beam is formulated in terms of an array radiating in free space or radiating in front of an impenetrable conformal or impedance surface. The array elements are non-resonant radiators. The physical dimension of the array is typically smaller than the diameter of the branch-cut disk of the complex point source. The array excitation coefficients are determined by solving a matrix equation that enforces the condition that the array fields match the fields of the complex point source in the far zone. For conformal and impedance surfaces the additional condition of zero internal fields is imposed. The SVD provides a powerful tool for obtaining the best-behaved solution.
