We present a novel technique to integrate analytically the highest‐order terms of the Kernel of a low‐order curl‐conforming magnetic‐field integral equation (MFIE) operator. In the computation of the bistatic RCS of moderately small perfectly conducting sharp‐edged examples, we show that this curl‐conforming choice yields very similar performance to that of the MoM‐EFIE formulation and outperforms a MoM‐MFIE formulation based on the RWG basis functions, both with very accurate Kernel integration. © 2005 Wiley Periodicals, Inc.
