Concurrent Complementary Operators for Mesh Truncation in Frequency-Domain Simulations

The concurrent complementary operators method (C-COM), when used in the finite-difference time-domain method (FDTD), achieved levels of accuracy unprecedented in any previous mesh-truncation technique. In this paper, we introduce the extension of the C-COM theory to frequency-domain (time-harmonic) simulations. A validation of the new method is demonstrated by using the finite-difference frequency domain (FDFD) method.
