Abstract: The Concurrent Complementary Operators Method (C-COM) has been demonstrated to be a highly effective mesh truncation technique for 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 Liao ABC and show that high accuracy can be obtained.
