A Study on the Electromagnetic Properties due to Circuit Patters in the Printed Circuit Hoard using Computer Simulation

컴퓨터 시뮬레이션을 이용한 PCB기판에서의 회로패턴에 따른 전자기적 특성에 관한 연구

In this paper, electric field interference was analyzed in the Printed Circuit Board to restrain the elcctromagnetic wave using Boundary Element Method and Finite Element Method. First, charge density distribution was simulated using Boundary Element Method and the characteristic impedance was caculated to restrain the reflex wave, and mutual capacitance was caculated in the multi-strip line PCB. Finally, electric field was simulated in the variable patterns using Finite Element Method. As a result, the optimal structure and characteristics of strip line was obtained and the imformations about the optimal design pattern could be obtained with the analysing the feild distribution.
