Abstract

This paper proposes a 3-D finite-difference frequency-domain (FDFD) non-conformal domain decomposition method for solving three dimensional electromagnetic problems. The proposed method allows modeling individual domains independently using the FDFD method with non-matching meshing grids at interfaces. Field continuity at interfaces between domains are enforced by introducing Lagrange multiplier and vector basis functions at the interfaces. The accuracy and efficiency of the proposed approach are demonstrated by numerical results for simulation of redistribution layer transmission lines on lossy silicon interposer.
