Paper Abstract

In this paper, by establishing a liquid crystal model of beam steering, a rapid iterative algorithm called Rosenbrock algorithm is proposed for obtaining wave-control data of liquid crystal phased array (LCPA). The method doesn’t need wavefront reconstruction, the error is reduced, and the searching direction is adjusted automatically to right space of solution, thus the algorithm converge rapidly, and the performance of beam steering is optimized at the same time. In this paper, firstly, a liquid crystal model of beam steering is established. Then, the effectiveness and superiority of this algorithm is verified compared with Pattern Search algorithm. Finally, we evaluate our algorithm by experiment. The results show that Rosenbrok algorithm can optimize the efficiency of beam steering rapidly and significantly.
