Reflection of Electromagnetic Waves from Bigyrotropic Negative Metamaterials
Yu. S. Dadoenkova,I. L. Lyubchanskii,이영백 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.3
Reflection of electromagnetic waves from the planar interface betwen a bigyrotropic negative magneticmedium(BNMM)and free space at incident angles close to the Brewster angle (BA) was investigated when the medium was magnetized perpendicularly to the interface. A BNMM has both permitivity and permeability tensors with off-diagonal components, which are induced by the magnetization M. We calculated the reflection coefficients for the vacuum-BNMM interface and obtained the equations for the BA and the pseudo-BA(PBA) for s- and p-polarized incident light. The angle of incidence for incident s- (or p-) polarized incident light, which gives the minimal (but not zero) intensity of the p- (or s-) polarized reflected light is called the PBA. We showed that only PBAs are posible for al magneto-optical configurations. The numerical values of the PBAs for different permitivity and permeability tensors were analyzed.

N. N. Dadoenkova,I. L. Lyubchanskii,M. I. Lyubchanskii,Th. Rasing,Sung-Chul Shin 한국자기학회 2000 Journal of Magnetics Vol.5 No.1
We have theoretically investigated changes in reflection coefficients induced by misfit strain located near the interface between an iron-yttrium garnet magnetic film and a nonmagnetic gadolinium-gallium garnet substrate in a transverse magneto-optical configuration.
A one-dimensional photonic crystal with a superconducting defect layer
Lyubchanskii, I L,Dadoenkova, N N,Zabolotin, A E,Lee, Y P,Rasing, Th Institute of Physics Publishing in association wit 2009 Journal of optics A, Pure and applied optics Vol.11 No.11
<P>A one-dimensional dielectric photonic crystal with a complex defect layer, consisting of ultrathin superconducting and dielectric sublayers, is theoretically studied. It is shown that the position of the defect mode and the transmittivity at the defect mode frequency strongly depend on the thickness of the superconducting sublayer as well as on the temperature.</P>
