Abstract
The spectrum of magnetoplasma oscillations of a two-dimensional electron layer in a bounded screened system is studied. It is shown that under certain conditions there exist oscillations whose frequencies are considerably lower than the electron cyclotron frequency. The wave-guide-type electromagnetic oscillations are described, whose frequencies experience in a strong magnetic field a shift and a splitting which are inversely proportional to the external magnetic field and to the transverse dimension of the system.
