The definition of Wavelet Analysis is that shifting the mother wavelet e.g. which has limited energy, such as shifting for, then proceeding dimensions, we obtained wavelet basis function ,, which make the inside product to the function to analysis With the Fourier transformation to the and, then the equivalent frequency spectrum of wavelet transformation can be expressed as where 、 are the transformations of 、 respectively and i is an imaginary number unit.

小波变换的含义是：把一具有有限能量的母小波，如进行移位后，再进行尺度的伸缩得到小波基函数为然后与待分析的函数作内积，即对和作Fourier变换后，可得到小波变换的等效频域表示为：其中、分别是、的Fourier变换，i为虚数单位。

Using the finitedifference timedomain electromagnetic method and c language program in the matlab software,the spatial electromagnetic field distribution radiation of photoconductive dipole antenna is calculated and displayed on the computer in a pseudocolor graph.

研究了光电导天线产生太赫兹波的辐射特性，利用麦克斯韦方程及其边界条件，计算了近远场的电场强度；采用电磁波时域有限差分方法，在Matlab系统软件中，用C语言编写程序计算光电导偶极天线的辐射太赫兹波的空间电磁场分布，并在计算机上以伪彩色图形显示，这种电磁场的可视化结果为天线的设计和改进提供了直观的物理依据。
