  "abstract": "The magnetocapacitance of a two-dimensional electron system (2DES) is investigated experimentally, both under and away from Quantum Hall (QH) conditions, at frequencies between 1 kHz and 100 MHz. The nature of the capacitive signal in a bounded 2DES is determined by a resistive cut-off frequency 1/$\\tau \\propto \\sigma_{xx}$, the longitudinal magnetoconductivity. A new response mechanism is reported for angular frequencies $\\omega > 1/\\tau$, which is controlled by the $\\em transverse$ or Hall conductivity $\\sigma_{xy}$ and the boundaries of the sample, even at frequencies far below those of the Edge Magnetoplasma resonances and away from the QH-conditions.",
