电磁波电场强度的取向和幅值随时间而变化的性质，在光学中称为偏振。如果这种变化具有确定的规律，就称电磁波为极化电磁波（简称极化波）。如果极化电磁波的电场强度始终在垂直于传播方向的（横）平面内取向，其电场矢量的端点沿一闭合轨迹移动，则这一极化电磁波称为平面极化波。电场的矢端轨迹称为极化曲线，并按极化曲线的形状对极化波命名。因此如果E的失端轨迹是圆，则此电磁波称为圆极化波。(The properties of the orientation and amplitude of the electric field intensity of electromagnetic waves vary with time, which are called polarization in optics. If this change has a definite law, the electromagnetic wave is called polarization electromagnetic wave (called polarization wave). If the electric field intensity of the polarized electromagnetic wave always orientations in the plane perpendicular to the propagation direction, the terminal point of its electric field moves along a closed path. Then the polarized electromagnetic wave is called the plane polarized wave. The vector end track of the electric field is called the polarization curve and is named for the polarized wave according to the shape of the polarization curve. Therefore, if the lost track of E is a circle, the electromagnetic wave is called a circular polarization wave.)

MATLAB 入门的教程，适合新手学习使用(this is for matlab new learners)

说明：  MATLAB示例代码 从2004年11月起，《MATLAB及在电子信息课程中的应用》的下载程序dsk01改为dsk02。两者只有微小的差别。主要的修改是： 1． 所有的生成图形都由灰色改成白色，以便与书籍上的图相同。 2． 删去了几个无用的程序； 3． 加了了几个程序（如q48a和q48b），以便和书上的章节演示内容相符。(MATLAB sample code from November 2004 onwards, "MATLAB and electronic information in the curriculum of" download dsk01 dsk02 changed. Taken only a very small difference. The major changes are : 1. All graphics generating replaced by gray and white, with the books to the same map. 2. By deleting a few useless procedures; 3. The increase in the number of procedures (such as q48a and q48b), and to book chapters on the demonstration line content.)
