Abstract
Within dissipationless limit the magnetic field
dependence of magnetoplasmon spectrum for unbounded 2DEG system
found to intersect the cyclotron resonance line, and, then
approaches the frequency given by light dispersion relation.
Recent experiments done for macroscopic disc-shape 2DEG systems
confirm theory expectations.
