Abstract :
The transient analysis of cylindrical cloaking structures using the Method of Moments (MoM) is accelerated in different ways. First, the periodicity along the axis is exploited through the use of the periodic Green´s function and the cyclic symmetry is exploited with a DFT-based method. MoM impedance matrix interpolation is used to accelerate frequency-domain sweeps. Finally, The Macro Basis Function (MBF) is combined with the multipole method to expedite the computation.
