The IMBERT-FEDOROV Shift Of Circularly Polarized Light Beam On The Surface Of Left-handed Materials

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.
