NONSTATIONARY EXCITATION OF OPEN STRUCTURES

Authors: Davidovich M. V.
The nonstationary theory of excitation for open resonators, waveguides and waveguide transformers has been developed. The open structures which are contained dielectric, magnetic and metallic bodies have been considered.

ANISHCHENKO-ASTAKHOV SELF-SUSTAINED OSCILLATOR AS ONE OF THE BASIC MODELS OF DETERMINISTIC CHAOS

Authors: Anishchenko V. S., Vadivasova T. Е.
In the present review the conditions of appearing chaotic self sustained oscillations are formulated and a radio-technical scheme of a generator realizing these conditions is given. The equations of Anishchenko-Astakhov's generator are derived and analyzed. A special attention is paid to the interrelation between the generator's equations and Theodorchik and Van der Pole classical models.

OPTICAL BIOMEDICAL DIAGNOSTICS

Authors: Tuchin V. V.
This paper presents an overview on optical biomedical diagnostics. It discusses briefly the history of the problem. The main attention is paid to description of the modern methods of optical medical diagnostics based on spectrophotometry, fluorescence, Doppler spectroscopy, elastic, quasi-elastic and Raman scattering spectroscopies, as well as optothermal and optoacoustic effects.
