mode-matching technique
mode diffraction
Cayley transform
For the scalar problem of mode diffraction on the abrupt waveguide discontinuity the Fresnel formulae for the reflection and transmission matrix operators are derived using the mode-marching technique. This generalized form of the matrix model is an immediate corollary of the proposed new statement of the problem. Making use of the energy conservation law in operator form, the correctness of the obtained Fresnel formulae for the scattering operators is proved analytically. Thus, the developed approach makes it possible to substantiate completely the widely used mode-matching technique for the class of diffraction problems under consideration.

tunneling
The diodes having a negative differential conductivity (NDC), due to the tunneling or resonance tunneling of electrons through the lateral diode faces is under consideration. These diodes can be used for frequency generation, amplification and multiplication. The condition for NDC realization, currents and current-voltage characteristics are determined. The problems supposed to be solved in the further investigations of diodes with tunnel- and resonance-tunnel side boundaries are set. The planar and sandwich-type diode structures are offered.

mesoscopic dissipative structures

phaser
The paper is devoted to computer modeling of evolution of mesoscopic dissipative structures (DS), which emerge in three-level excitable systems of the phaser type. Particular attention is given to the study of the rotating helical autowaves (RHA), including the stable RHA with multiple topological charges. The dimensional phenomena for these RSA have been revealed and investigated in details in the computer experiments. The hypersensitivity to the initial conditions is demonstrated for a multistable excitable system having spatial attractors in the form of RSA with various higher topological charges. The phenomenon of spatial coexistence of regular and irregular DS during slow transient processes in excitable medium has first been modeled (such a phenomenon observed before in real experiments on the ruby phaser).
