Abstract

In order to control the distribution characteristics of the far-field ring-shaped array, we introduce a new light source to produce adjustable far-field distribution by the method of weight function superposition. It has been shown that, by changing the parameters of the light source, one can obtain far-field with various distribution, including distribution with decrease in spectral intensity of specified rings, distribution with disappearances of specified rings, distribution with different spectral intensity of part of lobes in the continuous rings, distribution with part of the lobes in specified rings disappearing and distribution with some lobes in specified rings being stronger. These results will produce some novel far-field distributions which may provide a new idea for further study concerning about the manipulations of far-field array distribution.

根据权函数的叠加操纵远场环形阵列

为了控制远场环形阵列的分布特性，我们引入了一种新的光源，通过权函数叠加的方法产生可调的远场分布。结果表明，通过改变光源参数，可以得到多种远场分布，包括指定环光谱强度降低的分布、指定环消失的分布、连续环中部分叶片不同光谱强度的分布、指定环中部分叶片消失的分布和指定环中部分叶片增强的分布。这些结果将产生一些新的远场分布，为进一步研究远场阵列分布的操纵提供新的思路。
