The original poster seeks examples of applications where an electric field is scattered by a conductor in a two-dimensional context, mentioning a parabolic antenna as a reference point.
The discussion is ongoing, with participants providing different examples and clarifying the requirements of the original poster's question. There is no explicit consensus yet, as the original poster has specified a preference for conductors.
There is a focus on the definition of conductors in the context of electric field scattering, with some participants questioning whether the ionosphere qualifies as a conductor for the purposes of the original poster's request.
