V. A. Astapenko, F. B. Rosmej, E. V. Sakhno
The paper is devoted to the theoretical investigation of time dependences of quantum oscillator excitation by electromagnetic pulses for arbitrary values of field amplitude in the…
Dirac-graphene in slow-light
P. A. Golovinski, V. A. Astapenko, A. V. Yakovets
We obtained exact solutions for the wave function and the Green function in the slow light pulse with the group velocity, consistent with the Fermi velocity in graphene.
Reflection of a Broadband Electromagnetic Pulse by Planar Plasma Layer at Normal Incidence
P. A. Golovinski, V. A. Astapenko, E. S. Manuylovich
The problem of electromagnetic pulses propagation in plasma was studied in connection with various problems of radio engineering and radar systems. The description of propagation s…
The broadband pulse diffraction on a half-plane screen and caustic
P. A. Golovinski, V. A. Astapenko
The diffraction of ultrashort pulse changes its spatial and temporal structure that is crucial for multi-channel communication and location via such pulses. The features of the evo…
Diffraction of Ultrashort Pulse on a Nanoscale Conductive Cone
P. A. Golovinski, V. A. Astapenko, E. S. Manuylovich
Surface plasmon polariton is collective oscillation of the free electrons at metal dielectric interface. As a wave phenomenon, surface plasmon polaritons can be focused using appro…
Propagation of an ultrashort electromagnetic pulse in solid-state plasma
V. A. Astapenko, E. S. Manuilovich
The change of the shape of an ultrashort electromagnetic pulse in its propagation in solid-state plasma was calculated in the linear approximation. A case of solid-state silver pla…
The complex-valued encoding for dicision-making based on aliasing data
P. A. Golovinski, V. A. Astapenko
It is proposed a complex valued channel encoding for multidimensional data. The basic approach contains overlapping of complex nonlinear mappings. Its development leads to sparse r…
