Abstract
The excitation of magnetoplasmons in As-GaAs quantum dots and wires with far-infrared transmission spectroscopy is investigated. An interaction of the magnetoplasmon resonance with harmonics of the cyclotron resonance n (n=2,3) is observed. Results of self-consistent calculations of the magnetoplasmon dispersion show similar effects when the lateral confinement of the electrons has a slight deviation from a parabolic form. Comparison of the results indicates a good qualitative agreement between experiments and models.
