Abstract
We report phase-sensitive measurements of microwave propagation throug h a high-mobility two-dimensional electron gas subjected to a perpendi cular magnetic field. Two types of configurations were used, one that allows all wave vectors q, and one that selects only specific q values . The spectrum of edge excitations was studied over a broad frequency span, which allowed us to observe the logarithmic dispersion of edge m agnetoplasmons.
