A molecular dynamics method is used to study the distribution of molecules of a ferroelectric smectic liquid crystal 4-decyloxybenzylidene 4''-amino 2-methyl butyl cinnamate in a nanocapsule with a fixed near-boundary layer under an externally applied electric field. The temperature dependence of the order parameter is obtained both in the presence and in the absence of the external electric field. The temperature of the smectic-C* to smectic-A phase transition in the capsule in the presence of the electric field is calculated. The variation of molecule distribution and molecule conformation under an applied electric filed is discussed.

Аннотация: By using a simple model we consider single-channel transmission through a double quantum dot that consists of two single dots coupled by a wire of finite length L. Each of the two single dots is characterized by a few energy levels only, and the wire is assumed to have only one level whose energy depends on the length L. The transmission is described by using S matrix theory and the effective non-Hermitian Hamilton operator H-eff of the system. The decay widths of the eigenstates of H-eff depend strongly on energy. The model explains the origin of the transmission zeros of the double dot that is considered by us. Mostly, they are caused by (destructive) interferences between neighboring levels and are of first order. When, however, both single dots are identical and their transmission zeros are of first order, those of the double dot are of second order. First-order transmission zeros cause phase jumps of the transmission amplitude by pi, while there are no phase jumps related to second-order transmission zeros. In this latter case, a phase jump occurs due to the fact that the width of one of the states vanishes when crossing the energy of the transmission zero. The parameter dependence of the widths of the resonance states is determined by the spectral properties of the two single dots.

Аннотация: We consider single-channel transmission through a double quantum dot that consists of two identical single dots coupled by a wire. The numerical solution for the scattering wave function shows that the resonance width of a few of the states may vanish when the width (or length) of the wire and the energy of the incident particle each take a certain value. In such a case, a particle is trapped inside the wire as the numerical visualization of the scattering wave function shows. To understand these numerical results, we explore a simple model with a small number of states, which allows us to consider the problem analytically. If the eigenenergies of the closed system cross the energies of the transmission zeroes, the wire effectively decouples from the rest of the system and traps the particle.

Аннотация: We demonstrate the possibility of using transparent conducting oxides [aluminum-doped zinc oxide (AZO), gallium-doped zinc oxide (GZO), indium tin oxide (ITO)] to form Tamm plasmon polaritons in the near-infrared spectral range where the permittivity of oxides is near zero. The spectral properties of the structures are investigated in the framework of the temporal coupled-mode theory and confirmed by the transfer matrix method. It is found that in the critical coupling conditions, the maximal Q-factor of a Tamm plasmon polariton is achieved when a photonic crystal is conjugated with the AZO film, while at the conjugation with the ITO films, the broadest spectral line is obtained. The sensitivity of the wavelength and spectral width of the Tamm plasmon polariton to changes in the oxide film thickness, bulk concentration of a dopant, and angle of incidence is demonstrated.

Аннотация: Structure and magnetic properties of Co nanoparticles in the high-porous amorphous carbon matrix are presented. The average size of cobalt particles is 20 nm. The Co nanoparticles are ferromagnetic and characterized by the local magnetic anisotropy fields Ha = 10 kOe. The material consists of Jcc and hcp Co phases and highly defective phase with high concentration of stacking faults. There are no variations observed in the line shape of the NMR spectrum of Co particles at different temperatures. This implies that there are no polymorphous transfonnations inside Co particles with temperature.

Аннотация: The magnetic and resonance properties of CoNi(P) alloys, synthesized by chemical deposition as films on single crystal silicon substrates and as filaments in linear pores of porous silicon substrates, were studied by magnetization and ferromagnetic resonance measurements. It is established that CoNi(P) alloys of the same composition but different morphologies occur in states characterized by different degrees of nonequilibrium, which is manifested by different modes of the magnetization approach to saturation.

Кл.слова (ненормированные):
composite material -- anisotropic permittivity -- oblate and prolate particles -- depolarization factors
Аннотация: The concentration dependences of the effective permittivity have been obtained for an anisotropic composite consisting of a dielectric matrix filled with codirectional particles in the form of oblate or prolate ellipsoids of revolution (spheroids). The calculation has been made by solving numerically a system of coupled quadratic and integral equations obtained using the rigorous modification of the quasi-static Bruggeman theory. It is shown that the traditional simplified modification of the Bruggeman theory, which is widely used for calculating anisotropic composites, leads to errors of different signs for electromagnetic waves of the longitudinal and transverse polarizations relative to the spheroid axes. The dependences of the errors on the particle concentration are nonmonotonic and extrema observed in them can exceed 100%. The positions and values of the extrema depend strongly on the ellipticity of particles and the contrast of their permittivity with that of the matrix.

Аннотация: Faraday rotation (FR) spectral, field, and temperature dependencies in oxide glasses with small additions of paramagnetic elements are investigated. Formation of ferrite nanoparticles in amorphous glass matrices is revealed by X-ray diffraction. Particles have crystal structure similar to spinel structure, their dimensions are about 10-24 nm. The FR field dependencies are typical for ferrimagnetic or superparamagnetic substances depending on particle size. Strong FR increase at the samples cooling (more than twice for some samples) in the temperature interval 105-273 K is observed. (C) 2001 Elsevier Science B.V. All rights reserved.

Аннотация: The paper examines the characteristics of the miniature sensor of weak magnetic fields on the resonant microstrip structure with a thin ferromagnetic film. The authors calculated the frequency response of irregular microstrip resonator containing anisotropic magnetic film in quasi-static approximation. The resonator is connected to transmission lines via coupling capacities. The authors determined the optimal directional angles of the constant magnetic displacement field ensuring maximum sensitivity of the sensor. They examined the impact of angular and amplitude dispersion of uniaxial magnetic anisotropy of thin film upon the sensor characteristics. The regularities determined in this research qualitatively agree with the experimental results.

It has been found that, with an increase in the volume concentration of particles in the composite to ~33%, the real part of its permittivity increases from 2.6 to ~103, while the loss tangent remains no higher than 10–2 up to a frequency of 1 THz. We show the possibility of designing bandpass filters based on composite layered structures, which can be tuned by selecting the particle concentration in the quarter-wavelength layers of the mirrors that ensure the optimal interaction of half-wavelength resonators with each other and the outer resonators with free space. The high contrast between the matrix and the composite permittivities makes it possible to create mirrors with a required reflectivity using a minimum number of layers.

Аннотация: A structure based on porous anodic alumina with through pores is synthesized. This structure may be of some interest in terms of fabricating electrically switchable membranes. Conducting tubulenes connected to a common input electrode are located in the pores of the structure. It is hypothesized that enhancement of the electric field nonuniformity associated with the indicated structure morphology should help raise the degree of ionic selectivity of the membrane and broaden the range of permissible concentrations of ions in the processed solution. An suggestion regarding the structure of synthesized tubulenes in the context of the problem of suppressing the physical sorption of ions on the pore surface and raising the hydrogen and oxygen reduction potentials relative to those of state-of-the-art field-switchable membranes is also made.

Аннотация: Splitting of a Tamm plasmon polariton at the interface between a metal and a nanocomposite layer conjugated with a photonic crystal (Bragg mirror) has been theoretically investigated. The splitting can be implemented when the Tamm plasmon polariton frequency approaches the resonance frequency of the nanocomposite, which consists of metallic nanoballs dispersed in a transparent matrix. The reflectance spectrum of the p-polarized waves at the normal incidence of light has been calculated. It has been established that the Tamm plasmon polariton splitting significantly depends on the concentration of nanoballs in the nanocomposite layer and its thickness. The solution of the dispersion equation derived for a sample with semi-infinite mirrors has been compared with the spectra obtained for a finite structure by the transfer matrix method.

Spectral position control of dye absorption band maximum in an orienting matrix / E. M. Averyanov, V. A. Gunyakov // Molecular Engineering. - 1992. - Vol. 1, N. 4. - P. 311-316
Аннотация: The continuous control of the maximum position να of the dye absorption band (the zero of the derivative dD α(ν)/dν of the cell's optical density D α(ν)) in a nematic matrix is demonstrated experimentally, as a result of changing the angle α between the optical axis of a planar-oriented sample and the plane of polarization of absorbed light incident normal to the optical axis. The theory proposed describes quantitatively the experimental dependence ν(α). The rotation of the polarizer with given frequency ω results in the spectral position modulation of the solute band maximum ν(ω) within ν(α=0°)−ν(90°)=700 cm−1.
