Abstract

In this paper, the FDTD technique is applied to the common mode radiation analysis of a printed circuit board. In the past, the FDTD technique had limitations in its applications to such problems due to poor absorbing boundary condition performance. A highly efficient implementation of an extended PML absorbing boundary condition is formulated and applied to the PCB in this paper. Results are given for some common PCB geometries which demonstrate various common mode current phenomena as well as the accuracy of this technique
