Abstract :
Composite finite perfectly conducting (PeC) arrays of thin strips and Split Ring Resonators (SRR) with a Method of Moments integral formulation and triangular patches have been analyzed numerically. This paper presents the effect on the accuracy of the solution due to the type of meshing of the SRRs, the stopping residual error of the iterative algorithm GMRES and the accuracy of the PeC-EFIE operator.
