摘要
针对电磁场与电磁波课程教学中理论性强、概念抽象等特点,利用Matlab强大的数值计算和图形技术,从电磁场和电磁波传播两个方面,通过具体实例进行仿真,绘制了静电场电偶极子及同轴电缆线电场线、等位线分布图,形象再现了自由空间平面电磁波和球面电磁波的空间传播传播状态,有助于学生对电磁场和电磁波基本规律的掌握。
According to the characteristics of theory of strong and abstract concept in electromagnetic field and wave teaching, it is utilized graph and numerical technology of MATLAB software to simulate some typical examples from electromagnetic field and wave propagation in this paper. In the static electromagnetic field, it is draw up equipotential line and the electricity field pattern of electric dipole, as well as those lines of internal coaxial cable line; In the electromagnetic wave propagation, it is draw up plane electromagnetic wave and spherical wave station diagram propagation in free space. Based on simulation examples above, it is used to help students to comprehend and grasp laws on the electromagnetic field and wave.
