Abstract
A recently developed compression and sparse solution strategy for electromagnetic problems is applied to integral-equation formulations of scattering from perfectly conducting targets in three dimensions. It is shown that the resulting representations of both the impedance matrix and its inverse are sparse at low-to-moderate frequencies. Limitations and possible extensions of the sparse algorithms are also discussed.
