Abstract
The behavior of a capacitorlike device made of a circular metallic disk on a dielectric substrate over a ground plane is analyzed. A model of the device is derived from energy-flow considerations based on fundamental electromagnetic equations. Simulation results in both the frequency domain and the time domain are presented and compared with the predictions based on the ordinary quasi-static model. A salient feature of the device, revealed by the electromagnetic model, is that at very high-frequency regimes its behavior alternates periodically from capacitive to inductive. Limitations of the model are also discussed. © 2006 Wiley Periodicals, Inc. Microwave Opt Technol Lett 48: 1467–1472, 2006; Published online in Wiley InterScience (www.interscience.wiley.com).
