一种用于单向发射的非对称谐振腔的优化方法

An Optimization Method of Asymmetric Resonant Cavities for Unidirectional Emission

Fang-Jie Shu, Chang-Ling Zou, Fang-Wen Sun

摘要:

本文研究了一种非对称谐振腔(ARC)半四极半圆形状腔的射线模拟的重复性和精度,证实了方向性对形状误差的鲁棒性。在此基础上,我们提出了一种爬山算法,以优化的ARC单向发射。对不同的方向性评价函数进行了试验,建议对高度准直、单向的离子发射采用一定角度内的能量函数。利用这种方法,我们优化了ARC,在发散角为40 °时,远场辐射能量约占总辐射能量的0.46。这种优化方法是非常强大的ARC的形状工程,并可以应用于未来的研究与特定的发射性能的ARC。

英文摘要:

In this paper, we studied the repeatability and accuracy of the ray simulation for one kind of Asymmetric Resonant Cavities (ARCs) Half-Quadrupole-Half-Circle shaped cavity, and confirmed the robustness of the directionality about the shape errors. Based on these, we proposed a hill-climbing algorithm to optimize the ARCs for unidirectional emission. Different evaluation functions of directionality were tested and we suggested using the function of energy contained in a certain angle for highly collimated and unidirect ional emission. By this method, we optimized the ARCs to obtain about 0.46 of the total radiated energy in divergence angle of 40 degree in the far field. This optimization method is very powerful for the shape engineering of ARCs and could be applied in future studies of ARCs with specific emission properties.
