The concurrent complementary operators method (C–COM) has been demonstrated to be a highly effective mesh truncation technique for the simulation of electromagnetic open‐region transient or time‐harmonic problems. In previous work, the C–COM was applied to analytically derived absorbing boundary conditions (ABCs). In this work, we show that the C–COM can be applied to the wider class of highly effective and versatile numerically derived ABCs. As a demonstration of the validity of this generalization, we consider the case of a Liao ABC, and show that high accuracy can be obtained. © 2002 John Wiley & Sons, Inc.
