Abstract :
In this paper, we present an efficient technique based on the extension of the Adaptive Integral Method (AIM) that allows the full-wave analysis of microstrip reflectarrays. The reflectarray patches can have arbitrary shape and orientation and are modelled with subdomain triangular basis functions. The method makes use of a 2D-FTT/CG scheme, reducing the CPU time per iteration to 0(N logN) and the memory requirement to O(N).
