This approach allows us to easily control the parameters of a system and predictably change its optical properties, expressing the necessary conditions in an analytical form. The data obtained with the help of effective medium formula show that a heterogeneous medium with plasmonic impurities, such as silver nanoparticles with a concentration of about 10^21 particles per m^3, is new and interesting object of research with many perspectives for applications. Such plasmonic medium can be used as a transparent anti-reflection coating, weakly reflecting light-absorbing filter, or polarizing beam splitter with high performance in transmission and reflection. It is shown also that an extraordinary refractive index neff=1 in a heterogeneous medium with metal nanoparticles at transparency can be reached with the compensation of absorption at metal nanoparticles by the amplification in the matrix, and in the case of nonspherical nanoparticles the values of the gain necessary for compensation of absorption are smaller.

Research paper thumbnail of Defect modes of one-dimensional photonic-crystal structure with a resonance nanocomposite layer

Effective optical characteristics of the nanocomposite material have resonance singularities in the visible region of the spectrum, which are conditioned by the surface plasmon resonance of metallic nanoparticles. It is shown that the spectral profile of the energy bandgap of the photonic structure can be modified by varying the volume fraction and size of nanoparticles. The interrelation of splitting and shift of defect modes with structural parameters of a nanocomposite layer is studied by means of a numerical-graphical method with allowance for the frequency dependences of phases and amplitudes of reflectances in Bragg mirrors.

It has been shown that the number of optical resonances of the nanostructure and the detuning of the resonance frequencies from the eigenfrequency of the atom are only determined by the internal parameters of the nanostructure. The dependence of the number of resonances on the number of atoms in the nanostructure has been established. For nanostructures having a symmetry center, the number of resonances in atoms depends also on the orientation of the nanostructure axis with respect to the direction of external-wave propagation.

A theory is developed for description of the interaction between the probe of a near-field microscope and surface layers with widths much smaller than the wavelength of the incident radiation but much larger than the characteristic interatomic spacing. It is shown that, in the absence of resonance interaction between the microscope probe and the surface under study, the surface layers exert the main effect on the formation of the field in the near zone. At the same time, in the region of resonance interaction, the properties of the system are determined by the effect of both the surface layer and the semi-infinite underlying medium.

The conditions are analyzed under which the optical characteristics of the composite with axial symmetry of the inclusion orientation distribution with respect to a certain preferential direction significantly depends on the electric field direction in the electromagnetic wave. It is shown that, in the vicinity of the plasmon resonance of inclusions, the composite layer of subwavelength thickness may exhibit a high polarization selectivity in both reflection and transmission with moderate absorption. The effect of the orientational disorder of inclusions on the optical characteristics of a polarization splitter of this kind is discussed. The predictions based on equations of quasi-electrostatic effective-medium model agree well with the results of exact numerical solution of the Maxwell equations.

The conditions for the generation of slow surface plasmon waves of the terahertz (THz) and far infrared range propagating along the nanotubes of the irradiated array are determined. It is shown that the plasmon frequency can be controlled by changing the angle of incidence of laser radiation on the structure under study. Thus, it is possible to fulfill the condition of longitudinal resonance, in which each array nanotube is a dipole antenna radiating at the plasmon frequency. In this case, the array forms a system of a large number of inphase emitters, which allows increasing the efficiency of conversion of laser radiation into THz radiation in comparison with a single nanoantenna.

It is shown that under the synchronism condition a surface plasmon polariton amplification mechanism is implemented due to the transfer of electromagnetic energy from a drift current wave into a terahertz surface wave propagating along the surface of a singlewalled carbon nanotube. Numerical calculations show that for a typical carbon nanotube surface plasmon polariton amplification coefficient reaches huge values of the order of 10 6 сm −1 , which makes it possible to create a carbon-nanotube-based spaser.
