Research output: Contribution to journalArticlepeer-review


A normalized three-dimensional (3-D) multilevel fast multipole algorithm (MLFMA) with a computational complexity of O(N) for very low-frequency (LF) problem is developed. This 3-D LF-MLFMA can be used not only independently for very low-frequency cases or very small structures compared to the wavelength, but also to solve large-scale structures with rapidly varying areas when merged with a general dynamic algorithm. From the LF-MLFMA, a more explicit and succinct representation of the static MLFMA is also derived.
