heal.abstract	Metallic wedges can be considered as parts of corner reflectors, open-ended waveguides, transmission lines and other devices with polygonal shape existing in an electromagnetics laboratory. The fields developed in the vicinity of these conducting edges possess substantial magnitudes which can affect negatively the conducted experiments and the measurement procedures. In this work, a cylindrical cap of lossy material is used to weaken the damaging radiation of the edge. The influence of the cylinder's radius, the material's permittivity and conductivity and the angular extent of the wedge on the interfering field is illustrated through various numerical examples. © 2009 - IOS Press and the authors.
