10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM 2010). 2nd IEEE International Workshop on THz Radiation: Basic Research and Applications (TERA 2010)
The one-dimensional dielectric photonic crystals with complex defect layers, consisting of ultrathin superconducting and dielectric sublayers are theoretically studied. The pronounced difference in the transmittivity spectra of the photonic crystals with right-handed and left-handed positions of the superconducting defect sublayer with respect to the dielectric defect sublayer is demonstrated. The...
Damping of the polar vibrations determines the real limits of negative dielectric permittivity (DP) region as shown in this work. We obtain the simple quantitative criterion for the negative DP existence in the single oscillatory approximation model. We introduce this criterion as inequality between the damping constant and T-L frequency splitting of the polar phonon. This inequality is the sufficient...
The surface plasmon-polaritons and waveguide modes in prismatic structures are researched. The metallic layer is deposited on glass prism in the first structure and dielectric layer was deposited on metallic film in the second structure. The reflectance from the metallic layer equal zero at assiduously defined parameters. The first structure has high sensitivity of the minimum reflection angle; the...
A method of the coherent near-field sounding of multilayered dielectric structures is studied. It is based on field measurements with subwavelength probes (emitting and receiving) that are spaced in the near-field zone above the upper layer of the studied structure. It makes possible to achieve a subwavelength resolution at the control of the layers' depth. Especially high resolution can be achieved...
