光学中太保效应、近场、远场衍射matlab验证-CPIC effect optics, near field, far-field diffraction matlab verification

主要用于计算天线的近场和远场，计算天线的增益和有效孔径，做出天线方向图。-Mainly used to calculate the antenna near field and far field, calculate the antenna gain and the effective aperture, making antenna pattern.

fortran90编写的关于天线的小程序，实现了近远场变换及方向图的计算等-fortran90 write a small program on the antenna to achieve the near-far field transform and the calculation of the direction of Figure
