摘要
涡旋电磁波的产生方式有多种,使用涡旋相位板即为其中重要的一种方式。该文对螺旋相位板产生涡旋电磁波的情况进行了仿真.通过仿真。给出了在喇叭天线口面上覆盖螺旋相位板时生成的涡旋电磁波的幅度相位分布。
There are several methods to generate the vortex wave. The generating method based on spiral phase plate is an important one. This paper simulates the vortex wave generating based on the spiral phase plate. Through the simulation,the amplitude and the phase distribution maps of the vortex wave generated by covering the aperture of the horn antenna with spiral phase plate are given.
