In the high-speed signal path on PCB and packagings, vias usually causes most discontinuities and thereby crosstalks. In simulation and characterizations, they also generate more errors than the trace parts due to rich modes around them. To achieve both efficiency and accuracy, in this paper, a new domain decomposition based finite element time domain (FETD) method is proposed for the analysis of power/ground plate pairs with various types of antipads. Using the magnetic field feature, the 3D computational domain is firstly represented by a quasi-2D field. Then by taking advantage of the fast decaying property of high order modes, the …
