Abstract :
The complementary operators method (COM) has been successfully used for open-region mesh truncation in the finite-difference time-domain (FDTD) solution of wave propagation problems. The paper presents the development of frequency-domain complementary operators. The application requires two independent solutions of the problem. Despite this, computer memory and execution time can be saved by positioning the outer mesh-truncating boundary closer to the conductor than that required when using other techniques.
