GPU-accelerated synthesis of echo generators

We deal with an approach to the design of array based, 2D echo generators. The radiating elements are located on non-uniform grids and the Quiet Zone (QZ) design specifications are enforced at non uniformly spaced sampling locations. The radiating element positions and QZ design specification matching points are determined by a singular values optimization process. In order to properly manage the computational burden, a proper parallel programming strategy is employed, in particular, by exploiting the potentialities recently offered by Graphics Processing Units (GPUs) through the Jacket Matlab toolbox. Numerical results assess the performance of the technique in terms of computational requirements and QZ field behavior.
