Nested Pseudoskeleton Approximation Algorithm for Generating H 2 -Representation of Electrically Large Surface Integral Operators

In this paper, we develop a fast nested pseudoskeleton approximation algorithm to generate a low-rank $\mathcal{H}^{2}$ -matrix to represent electrically large surface integral equations (SIEs). The algorithm only uses $O (N\log N)$ entries of the original dense SIE matrix of size $N$ to generate th... View More
