Summary:The electromagnetic scattering at a perfectly conducting object is usually initiated by an incoming electromagnetic field. It is well known that the classical boundary element implementations solving for the scattered electric field are not uniformly stable with respect to the frequency of the incoming signal. The subject of this article is to develop a stabilized boundary element formulation that does not suffer from the so‐called low‐frequency breakdown. The mathematical theory is verified by numerical examples. Copyright © 2012 John Wiley & Sons, Ltd.
