Influence of retardation effects on a 2D magnetoplasmon spectrum
Abstract
Within a dissipationless limit, the magnetic field dependence of the magnetoplasmon spectrum for an unbounded two-dimensional electron gas (2DEG) system was found to intersect the cyclotron resonance line and, then, approach the frequency given by light dispersion relation. Recent experiments done for macroscopic disc-shaped 2DEG systems confirm theoretical expectations.
