| Реферат: | eng: In this paper, a problem of taking into account the electromagnetic radiation power in a numerical simulation of electron beam-plasma interaction is considered. The numerical model is based on the particle-in-cell (PIC) method and the finite-difference time-domain (FDTD) scheme for solving Maxwell equations. As a boundary condition, it is proposed to use a simple layer of absorption, that is, artificial attenuation of an electromagnetic wave by multiplying the electromagnetic field in the boundary domain by a coefficient k < 1 depending on the distance to the boundary. The numerical experiments performed show that using such a layer for absorbing the electromagnetic radiation and for taking into account its power is efficient.
