摘要：

The collective properties of surface electron systems consisting of several lines of charges are considered. To simulate the system, its characteristic frequencies of oscillations are found by applying Fourier analysis to the average coordinates of particles along and across the lines. The frequencies are compared with the theoretically obtained dispersion laws of plasma modes, calculated according to the equations of motion for small displacements of electrons from equilibrium. The dispersion laws of collective oscillations are calculated for two-, three-, and four-chain systems of electrons, and in the latter case, configurations with both identical and different distances between the charge lines are examined. There is good agreement between the simulation results and the frequency values that follow from the dispersion laws.
