Abstract

The damped absorption as a boundary condition for solving the Maxwell equations by the FDTD (Finite Difference Time Domain) method is considered. Numerical experiments confirm the efficiency of using a simple absorbing layer to absorb the electromagnetic radiation from a point source. The efficiency of using this method to take into account the power of electromagnetic radiation in the numerical simulation of electron beam-plasma interaction by the particle-in-cell method is also shown.
