Abstract :
We discuss one of the computationally most critical steps of the Phase-Only synthesis of aperiodic reflectarrays, namely the fast evaluation of the radiation operator. We present its implementation by using a 2D Non-Uniform FFTs (NUFFTs) of NED (Non-Equispaced Data) type on Graphic Processing Units (GPUs) in Compute Unified Device Architecture (CUDA) language. We also illustrate the programming strategies used to speedup the code, including the use of dynamic parallelism made available by the latest architecture of CUDA cards.
