Title
(EN) Method for synthesizing vortex electromagnetic field with high orbital angular momentum mode number
(ZH) 一种合成高轨道角动量模式数的涡旋电磁场的方法
Abstract
(EN) The invention relates to a method for synthesizing a vortex electromagnetic field with a high orbital angular momentum mode number. The method for synthesizing the vortex electromagnetic field comprises the following steps: N antenna units form a circular antenna array, and by rotating the circular antenna array and regulating and controlling the phase of each antenna unit, the vortex electromagnetic field is synthesized, wherein N is an integer larger than or equal to 1. By utilizing the method provided by the invention, the synthesized vortex electromagnetic field with the target mode numbercan be generated as required, and the vortex electromagnetic field with the high mode number is directly synthesized by rotating the antenna array and regulating and controlling the phase of each antenna unit under the condition of a small number of antennas, so that the resolution of the imaging system in the azimuth direction is increased. The vortex electromagnetic field synthesized by using the method disclosed by the invention not only is beneficial to realizing super-resolution imaging, but also has remarkably improved modal purity, and has a very good application prospect in the fieldsof super-resolution biomedical imaging, radar imaging, wireless communication and the like.
(ZH) 本发明涉及一种合成高轨道角动量模式数的涡旋电磁场的方法。具体提供了以下合成涡旋电磁场的方法:将N个天线单元构成圆型天线阵列,通过旋转圆型天线阵列、调控每个天线单元的相位,合成涡旋电磁场,N为大于等于1的整数。利用本发明的方法,能够根据需要产生目标模式数的合成涡旋电磁场,在较少的天线数量下,通过对天线阵列的旋转与对天线单元的相位调控,直接合成高模式数的涡旋电磁场,增加成像系统在方位向上的分辨率。利用本发明的方法合成得到的涡旋电磁场不仅有利于实现超分辨成像,还具有显著提高的模态纯度,在超分辨生物医学成像、雷达成像、无线通信等领域中具有非常好的应用前景。
