Dielectric photonic quasi-crystals with doubled quasi-periodicity, Journal of Telecommunications and Information Technology, 2000, nr 1,2

Optical range electromagnetic field interaction with inhomogeneous finite dielectric media is investigated. New method for analysis of this interaction in 1D case based on integral equations for fields in transient media is proposed. Some special cases of quasi-periodical structures with doubled quasi-periodicity are investigated numerically. A possibility to obtain good filtering properties in such structures for small number of quasi-periods is shown

Optical pulse splitting under temporal variations of reflecting medium, Journal of Telecommunications and Information Technology, 2000, nr 1,2

A possibility of light pulse transformation by transient reflecting medium is investigated theoretically. After solving 1D problem of such a reflection one estimates such a transformation in a plane optical waveguide with time-dependent conductivity of one of the reflected media. Three types of the conductivity time-dependences are considered: harmonic, Bessel-like and splash-like ones. Obtained results show a possibility of pulse splitting under an influence of time-harmonic conductivity and pulse collapse vy the other considered nonstationarities

New method of numerical modelling of optical field transformation by inhomogeneous semiconductor layer with time-varying parameters, Journal of Telecommunications and Information Technology, 2000,nr 1,2

A time-domain model of a semiconductor layer with time-dependent inhomogeneous permittivity or conductivity is investigated by solving direct and inverse problems using a novel method, revealing a possibility of wavelength shifting and other desirable optical field transformation, as well as a remote diagnostics of fast time-varying inhomogeneous structures

Recent advances in PBG structures, Journal of Telecommunications and Information Technology, 2000, nr 1,2

We propose a review of word science achievements in the extremely extended for the recent few years field of photonic band gap structures. The review concerns both theoretical and experimental investigations on PBG structures toward fabrication of the most optimal ones for different applications. The attention is given to the obtained results as well as to the used and developed methods
