【摘要】 本文介绍如何实现平行双导线(PWS)的电磁场分布特性三维可视化动态模拟。首先结合PWS传输特性的TEM波,将PWS电磁场关于空间分布与变化的数学描述进行离散化,然后进行C语言编程,直观地将PWS的电磁场分布以三维动态方式表现出来,电荷量动态可调,实现了将抽象公式与概念的可视化。教学效果表明,该方法既加深了学习者对平行双导线电磁场分布特性的理解,又提高了学习效率。更多还原

【Abstract】 The distribution characteristics and formula description of electric and magnetic field of the parallel wires( PWS) are analyzed in this paper. The discretization of mathematical formula of electric and magnetic field of the parallel wires is done according to the scientific calculation and simulation platform based on Cprogramming language environment. The dynamic transmission process of the internal electric field and the magnetic field around parallel wires are shown vividly,the formula and abstract concept of the field of electromagnetic are visualized. It can help the students understand the distribution characteristics and the theory of electromagnetic field coaxial wave guide in the teaching process,the efficiency of learning can also be improved.更多还原
