摘要
本文通过分析离散点电荷系统的电场得到相应电场计算公式,经由Matlab内置函数得到其电力线分布,并对所述的四种电力线绘制方法进行优缺点分析。同时还引入了波导系统在不同传输模式下的电力线分布,以证明利用Matlab进行电力线绘制的有效性。
Through the analysis of the electric field of discrete point charges systems, we obtain the corresponding formula for electric field and get distribution of this electric lines of force via the built-in function in Matlab. Then we analyze their advantages and disadvantages among the four methods. We also give the distributions of electric lines of force in waveguide systems under different modes to prove the effectiveness of our methods.
