This global analysis is achieved by using surface impedance to model the nonlinear element (GaN Schottky Barrier diode). These systems use the manufacturing processes of integrated circuits. In order to initialize the iterative procedure, an incident wave is defined in spectral domain. The numerical results are compared to those obtained with the measured one. The good agreement between simulated and published data justifies the design procedure. http://pubs.sciepub.com/iteces/2/1/3/iteces-2-1-3.pdf rectennaWCIPGaN Schottky barrier diodeRF2D-FFT algorithm
