| description | An enhanced hybrid technique combining the multilevel
fast multipole algorithm (MLFMA) and the physical optics
(PO) is presented for analyzing scattering and radiation by
electrically large structures. Based on the previously proposed
hybrid technique, an extra octree structure is built for the
moment method (MoM) region to accelerate the solving process
and an iteration scheme is proposed to further enhance the
efficiency compared to the conventional hybrid method. What
is more, the modified iterative physical optics (IPO) accelerated
by MLFMA technique is adopted to improve the accuracy by
simulating complex structures with strong reflections. Numerical
results are given to demonstrate the improved accuracy and
higher accuracy of the proposed hybrid technique compared to
the previous MLFMA-PO method. |
