Abstract

Abstract: A new kind of absorbing boundary conditions based on the theory of generalized Z-domain absorbing boundary conditions (Z-ABCs) for the 3D TLM SCN method is presented. The results indicate that the Z-ABCs show better performance than Higdon's ABC in suppressing instability caused by spurious modes. The different order coefficients of this new Z-ABCs can be given by a recurrence formula.

Key words: transmission-line method, generalized Z-domain absorbing boundary condition, microstrip, recurrence formula
