Abstract This paper presents the application of the nonuniform orthogonal mesh FDTD method combined with Mur's second‐order ABC to structures that have symmetrical planes. Particularly, it is revealed that, in order to combine Mur's second‐order ABC with a symmetrical plane, an alternate form of Mur's second‐order ABC,instead of its conventional form, has to be employed. The accuracy and efficiency of the proposed FDTD algorithm are confirmed by analyzing a slot‐loaded bow‐tie microstrip antenna that has experimental results for comparison. ©1999 John Wiley & Sons, Inc.
