A novel plasmonic polarization filter based on the diamond-shape photonic crystal fiber(PCF) is proposed. The resonant coupling characteristics of the PCF polarization filter are investigated by the full-vector finite-element method. By optimizing the geometric parameters of the PCF, when the fiber length is 5 mm, the polarization filter has a bandwidth of 990 nm and an extinction ratio(ER) of lower than -20 dB. Moreover, a single wavelength polarization filter can also be achieved, along with an ER of -279.78 dB at wavelength 1.55 μm. It is believed that the proposed PCF polarization filter will be very useful in laser and optical communication systems.

关键词： photonic crystal fiber polarization filter extinction ratio

由于分布式电源并网逆变器存在的低惯性、欠阻尼特性会影响电力系统稳定性,利用考虑发电机励磁与汽门综合控制的同步发电机四阶模型,设计了基于自适应Terminal滑模控制方法的虚拟同步发电机控制方案。针对系统的2个输入变量,构造了2个非奇异的Terminal滑模函数,由于Terminal滑模函数为非线性函数,使得误差可以快速收敛,从而保证了控制器良好的控制效果。仿真结果验证了所提控制策略可以为系统提供必要的惯性和阻尼,保证系统在参数不确定和存在外界扰动情况下的鲁棒性,能够抑制振荡并提高电力系统的稳定性。

目标机动是影响导弹制导性能的重要因素。文章以变结构制导导弹为研究对象,以导弹与目标相对运动方程为依据,就目标机动和变结构制导项对视线角速度和弹道需用过载的影响做了理论分析,提出了一种针对目标机动的变结构制导参数设计方法。在此基础上,提出用模糊控制理论设计变结构制导项。仿真结果表明,所设计的模糊变结构制导律能够有效抑制目标机动对制导精度的影响。
