The interaction of two one-dimensional spatial vector structures of a Bose–Einstein atomic condensate in a trap with significant transverse dimensions and oscillating walls has been simulated numerically. Different types of coupled structures and d

We computationally analyze the influence of random inhomogeneities of the interface surface between two media that are diagnosed by the pulsed THz spectroscopy method. The statistics of inhomogeneities is characterized by the rms dispersion and corre

We show that, for terahertz (THz) radiation, the effective focal length of a lens differs significantly from its geometrical-optics (nominal) focal length. As a pulse of THz radiation with a bell-shaped (Gaussian) transverse profile is incident on a

The dynamics of localized structures of atomic Bose–Einstein condensate in traps with oscillating walls has been analyzed. The properties of these oscillons localized in the longitudinal and transverse directions with respect to the trap axis are c

The parametric Doppler effect is analyzed and simulated numerically in the case in which a wave or a pulse of optical radiation interacts with an inhomogeneity overtaking it in a medium with frequency dispersion. It is shown that, as the velocity of

Localized structures forming in the bistable regimes in a chain of weakly coupled split ring resonators, which are the building blocks of a nonlinear magnetic metamaterial, where electric current is generated by external electromagnetic radiation, ha

The reflection of monochromatic and quasi-monochromatic pulsed light incident on a moving inhomogeneity in the optical characteristics of a medium having plasma-type dispersion has been analyzed. The velocity V of the inhomogeneity, induced in the me

A theoretical analysis and numerical simulation of a soliton collider (a wide-aperture laser with saturable absorption and variable length of the cavity) are performed. The presence of the cavity length gradient in a part of the aperture allows one t

A numerical analysis has been made of the motion of spatial dissipative soliton complexes in a wide-aperture interferometer with the Kerr nonlinearity, which is excited by continuous coherent driving radiation. It has been demonstrated that, dependin

Investigations of the motion of dissipative optical solitons and their complexes in wide-aperture nonlinearly optical (with coherent pump radiation) and laser (with incoherent pump radiation) systems have been reviewed. An important characteristic of
