Abstract

This article proposes a space power combiner based on the quasi-optical phase-correcting technology. The combiner consists of a couple of irregular-shaped reflective mirrors, by which the wave generated from waveguide horns can be modulated into a Gaussian-like beam to achieve the space power combining. The deformation of the mirrors is calculated using a modified Katsenelenbaum–Semenov algorithm. Performance of the space power combiner evaluated by simulation, and the results indicate that the power combiner features high efficiency and broad bandwidth.

基于准光学相位校正镜的空间功率合成器
提出了一种基于准光学相位校正技术的空间功率合成器。该组合器由一对不规则形状的反射镜组成,通过该组合镜可以将波导角产生的波调制成类高斯光束,从而实现空间功率组合。使用改进的Katsenelenbaum-Semenov算法计算反射镜的变形。通过仿真对该空间功率合成器的性能进行了评估,结果表明该空间功率合成器具有效率高、带宽宽的特点。
