【摘要】 近来,人们发现当光在左手材料中传播时会表现出一些奇异的电磁特性,因此,左手介质表面的Imbert-Fedorov位移也受到了人们越来越多的关注。本文采用能流法的思想,在理论上分别对圆偏振光入射时,各向同性均匀左手介质、各向异性左手介质和弱吸收左手介质表面的Imbert-Fedorov位移进行了研究。1.运用能流法推导出了圆偏振光从右手介质入射到各向同性均匀的左手介质表面时Imbert-Fedorov位移的表达式。并在此基础上讨论了Imbert-Fedorov位移随入射角度的变化关系以及圆偏振光的旋向不同对Imbert-Fedorov位移的影响。2 .分别对单轴各向异性左手介质和双轴各向异性左手介质表面的Imbert-Fedorov位移进行研究。在对单轴各向异性左手介质表面的Imbert-Fedorov位移进行讨论时发现,Imbert-Fedorov位移不仅与入射光束的性质和入射角度有关,而且与光轴的方向也有很大的关系。另外,给出了双轴各向异性左手介质表面的Imbert-Fedorov位移的表达式,并且讨论了当介电常数和磁导率不相同时,Imbert-Fedorov位移的变化趋势。3.讨论了弱吸收左手介质表面的Imbert-Fedorov位移。分别分析了Imbert-Fedorov位移随着介电常数的实部和虚部的变化规律,以及在单层膜结构下膜的厚度对Imbert-Fedorov位移的影响。更多还原

【Abstract】 There will be some particular electromagnetic characteristics when light beam propagates in left-handed materials . Therefore, Imbert-Fedorov shift at the interface between right-handed material and left-handed material received more and more attention. This thesis deal with the Imbert-Fedorov shift on the surface of homogeneous isotropic left-handed medium, anisotropic left-handed medium and weakly absorbing left-handed medium based on the Renard model when an circularly polarized light beam propagates in the medium theoretically.Firstly, the expression about Imbert-Fedorov shift is presented when an circularly polarized light beam is totally reflected at the interface between right-handed material and homogeneous isotropic left-handed material. On this basis, the relation between Imbert-Fedorov shift and the incident angle, the difference of Imbert-Fedorov shift when the circularly polarization is switched from left-hand to right-hand is also discussed.Secondly, the Imbert-Fedorov shift on the surface of uniaxially anisotropic left-handed material and biaxial anisotropic left-handed material is investigated theoretically. The results show that the displacement depends not only on the polarization and incident angle of the incident beam, but also on the orientation of the optical axis. In addition, the expression of Imbert-Fedorov shift on the surface of biaxial anisotropic left-handed material is presented. And does some discussion about state of Imbert-Fedorov shift when the permittivity and permeability are difference.Finally, Imbert-Fedorov shift on the surface of weakly absorbing left-handed medium is discussed. The thesis presents the behavior of Imbert-Fedorov shift with the variation of real and imaginary part of permittivity. At last, the relationship between the thickness of the dielectric film and the shift in the configuration of single layer film.更多还原
