Why can I not assign all the media I have added to my Media Library to the regions and faces of the objects in my FEKO models? What are the rules for assigning media to regions and faces of models? I was told in an email from the FEKO support team that a metal solid is modeled in FEKO not by setting the region of the object to a metallic medium (which is not allowed) but by making the region medium of the object free space, by making the medium of the object "surfaces" (by which I assume was meant "faces") the needed metallic medium, and by making the thickness of those "surfaces" greater than skin depth. I have tried this but the metallic medium I am using, copper, does not appear on all of the model faces I need to model as copper. I am using FEKO 7.0.
Hello everyone, I have a mode of a propeller in which I have only faces and edges. However, it is a 3D figure. When I want to make the medium of the model a dielectric medium, I get to choose between PEC, layered dielectric and default. The thing I do not understand is how can be a layered dielectric be a medium? Is it over a medium already? What exactly does it do when I select the medium as layered dielectric?
I have a simple doubt. I have a 2D polygon (XY plane) on my model and the incident plane wave and electric field is also on the same plane (XY plane) and the magnetic field is perpendicular to the plane XY (on z). Theoretically the monostatic RCS should be the same for a PEC and for a Free space medium inside the polygon as the wave can't penetrate inside. And, unfortunately I can't change the properties of the edges. Edges remains edges. I can't put any material for edges in the model. And, I get different results for a PEC and for a Free Space medium inside the polygon. Why? I have made a comparison on PEC and free space. Please help. 2Blades_comparison_4_GHz.eps
