We address the generation of complex near-field (NF) wavefronts through a two-step process involving the de-termination of an equivalent radiating panel and its practical implementation as an array. Our novel approach discretizes 2D radiating panels using an optimized, nonuniform 2D quadrature rule. The optimized quadrature nodes determine the array element locations, while the excitation coefficients are obtained using the Singular Value Decomposition (SVD). Numerical results demonstrate the effectiveness of the method in accurately generating NF waveforms.

Abstract
We address the generation of complex near-field (NF) wavefronts through a two-step process involving the de-termination of an equivalent radiating panel and its practical implementation as an array. Our novel approach discretizes 2D radiating panels using an optimized, nonuniform 2D quadrature rule. The optimized quadrature nodes determine the array element locations, while the excitation coefficients are obtained using the Singular Value Decomposition (SVD). Numerical results demonstrate the effectiveness of the method in accurately generating NF waveforms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
