The possibility is established and the conditions are found for localization of plasmon-polaritons (PPs) near the boundaries of hyperbolic metamaterials (HMs) of both I and II types with arbitrary orientation of the optical axis. It is grounded that such surface PP has the transverse spin momentum which depends on the wavelength of the exciting wave, the orientation of the optical axis of the hyperbolic metamaterial, and dielectric properties of bordered media.

Single Living Cells

Advances in digital imaging microscopy and in the synthesis of fluorescent dyes allow the determination of 3D distribution of specific proteins, ions, GNA or DNA in single living cells. Effective use of this technology requires a combination of optical and computer hardware and software for image restoration, feature extraction and computer graphics.The digital imaging microscope consists of a conventional epifluorescence microscope with computer controlled focus, excitation and emission wavelength and duration of excitation. Images are recorded with a cooled (-80°C) CCD. 3D images are obtained as a series of optical sections at .25 - .5 μm intervals.A conventional microscope has substantial blurring along its optical axis. Out of focus contributions to a single optical section cause low contrast and flare; details are poorly resolved along the optical axis. We have developed new computer algorithms for reversing these distortions. These image restoration techniques and scanning confocal microscopes yield significantly better images; the results from the two are comparable.

The Stability

Magnetic lenses operating in partial saturation offer two advantages in HVEM: they exhibit small cs and cc and their power depends little on the excitation IN. Curve H, Fig. 1, shows that the maximal axial flux density Bz max of one of the lenses investigated changes between points (3) and (4) by 5% as the excitation varies by 40%. Consequently, the designer can relax the requirements concerning the stability of the lens current supplies. Saturated lenses, however, can only be used if (i) unwanted fields along the optical axis can be controlled, (ii) 'wobbling' of the optical axis due to inhomogeneous saturation around the pole piece faces is prevented, (iii) ample ampere-turns can be squeezed into the space available, and (iv) the lens operating point covers a sufficient range of accelerating voltages.

Рассмотрен потенциал возможностей светотехнических мобильных навигационных комплексов, обеспечивающих дальний привод летательных аппаратов по глиссаде. Основа комплекса – ​суперяркие монохромные светодиоды производства компании ООО «НПЦ ОЭП «ОПТЭЛ». Для сравнения характеристик светодиодов для задач навигации выбран новый параметр – ​распределение освещенности в плоскости, перпендикулярной оптической оси светодиода. Параметр влияет на массо-­габаритные и тактико-­технические характеристики проектируемых изделий. The article discusses the possibility of creating lighting mobile navigation systems that provide long-range drive of aircraft along the glide path. System base – ​monochrome LEDs of LLC SPCOD “OPTEL”. A new parameter was proposed for navigation issues – ​the distribution of illumination in a plane perpendicular to the optical axis of the LED. The parameter affects the overall dimensions and tactical and technical characteristics of the designed products.
