提出了一种新的方法--低频快速非均匀平面波算法（LF‐FIPWA），将传统的多层快速多极子算法（MLFMA）和快速非均匀平面波算法（FIPWA）无缝地扩展到低频范围。它使用倏逝波外推和平移技术来克服低频击穿问题。精度可以在很宽的频率范围内得到很好的控制。数值算例表明了新算法的有效性。© 2004 Wiley Periodicals，Inc. Microwave Opt Technol Lett 40：117-122，2004;在线发表于Wiley InterScience（www.interscience.wiley.com）。DOI 10.1002/mop.11302
A new method, the low‐frequency fast inhomogeneous plane‐wave algorithm (LF‐FIPWA) is presented to extend the traditional multilevel fast multipole algorithm (MLFMA) and fast inhomogeneous plane‐wave algorithm (FIPWA) seamlessly into the low‐frequency range. It uses evanescent‐wave extrapolation and translation techniques to overcome the low‐frequency breakdown problem. The accuracy can be well controlled over a broad frequency range. Numerical examples show the effectiveness of this new algorithm. © 2004 Wiley Periodicals, Inc.
