abstract
The problem of a printed circuit board (PCB) via is analyzed through the scattering parameter and the flux methods. The two results are compared in an effort to establish the relationship between the two techniques and evaluate their contributions. A ground via in a one-port and two-port configuration is studied in the time and frequency domains using the finite difference time domain (FDTD) and the finite element method (FEM) respectively. The scattering parameters for the via configuration are computed and compared for validation purposes.<>
