激光致盲干扰效能分析研究

为了分析研究激光致盲干扰的作战能力,评估激光致盲干扰的作战效能,基于激光致盲干扰的干扰原理和干扰效果评估准则,采用效能评估分析方法,总结出激光致盲干扰的干扰方程,从干扰方程出发,提出了致盲距离、致盲概率两个效能分析指标,给出了概念、计算模型,并进行了理论分析和仿真验证。结果表明,激光干扰机的输出功率越高,光束质量越好,致盲距离就越大;激光干扰机的定位精度越高,致盲概率就越大,从而分析总结出影响激光致盲干扰效果的因素,为激光致盲干扰研究奠定了基础。

Study on band gap and waveguide coupling characteristics of air pattern photonic crystal

In order to study the relation between band gaps for TM and TE polarization of two dimensional air pattern photonic crystal and dielectric cylinder radius, the band gap distribution and waveguide coupling characteristics of air pattern photonic crystal was simulated with plane-wave expansion method. Results show the photonic crystal band gap varies with the dielectric radius, the optical wave confined in the photonic crystals can efficiently transmit in waveguides and resonator cavity so as to output optical wave selectively. These characteristics have important and potential application in photonic integrated circuits.
