| 摘 要： | 根据基尔霍夫衍射理论,对其衍射公式数值进行积分计算,推导出负折射平板折射率偏离-1时像点附近的光强分布,并用MATLAB画出了相应的光强分布图。研究表明,当折射率偏离-1时,像点附近的光强分布在z方向不再对称,但在x方向依然保持对称,不对称随折射率偏差增大而增大,像点光强变得较分散,且存在伴峰。如果把物点放在对应半径曲面的齐明点处,可以很好地消除球差,但像点位置与n′=-1时有所不同。

| Abstract: | Based on the Kirchholf diffraction theory,the slab imaging performances are studied for different negative refractive index deviating from-1,and the field patterns are drawn with MATLAB.The results show that when refractive index deviates from-1,the light-intensity distribution around the image point becomes asymmetric along z-axis,the fields are irregular and the satellite peaks occur.In addition,the aplanatic curvature radius r was found.The results show if the object point is put at the aplanatic point c... |
