Electromagnetic susceptibility analysis of PCBs using predictive method

Abstract

In this paper, a statistical approach is proposed for analysis of electromagnetic compatibility of printed circuit boards using trace orientation function. The board traces are one of the most responsible for radiated emission and susceptibility of the electronic system implemented on it. Trace orientation function, as a novel approach, is a random function which considers the arbitrary position and direction of traces on the board. To show the accuracy of the method, it is applied on a simple example and compared with full-wave simulation results. The moderate accuracy, predictive nature, and low computational cost of the method confirm the practicality of proposed statistical approach for electromagnetic compatibility analysis of complex modern circuit board with numerous components.
