Jm. Rius et al., ANALYSIS OF ELECTRICALLY LARGE CONCAVE SCATTERERS WITH THE INTEGRAL-EQUATION MEI, Microwave and optical technology letters, 14(5), 1997, pp. 287-289
The integral equation MEI (IE-MEI) is a new, sparse matrix formulation
of the boundary-element method, which is particularly well suited for
large convex scatterers. In this Letter we explain why the original i
mplementation of IE-MEI fails for large concave objects and propose a
remedy. (C) 1997 John Wiley & Sons, Inc.
