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 implementation of IE‐MEI fails for large concave objects and propose a remedy. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 14:287–289, 1997.
