Abstract

Abstract

An electromagnetic radiation (EMR) effect evaluation method is presented in this paper. The effect is ranked by the weighted average of the coupled electric field with domain decomposition and subdomain sensitive factors. Meanwhile, a facilitated electromagnetic model of a general purpose computer motherboard is built. Numerical simulation based on the Finite-Difference Time-Domain (FDTD) method is performed and the coupled electromagnetic field of the motherboard is achieved. EMR with incident angle from 0° to 90° at frequency from 3 GHz to 12 GHz is simulated and their effects are compared based on the developed evaluation method. Numerical results show that: (a) The larger the EMR incident angle is, the weaker the EMR effect is. The maximum weighted average of electric field is obtain
