I am trying to carry out eigen mode solution upon a corrugated trapezoidal structure. I used metal and it shows solving inside a solid with high conductivity may require a large mesh in hfss. I have applied master slave boundary condition, want to carry the sim using metal. since i have a corrugated structure the whole objects became one. "not checking solve inside" is not of help. mesh operations should be defined. i need help badly.
i want to find out the reflection profile of a trapezoidally corrugated slow wave structure. for that i have to excite the structure with a antenna.how do i do that?

You can excite the structure with an incident plane wave for the general case. Use an antenna if you need a specific setup, but the simulation will be much larger.

Yes. You need to insert a measurement plane. (Scattered Real Power/ Incident Real Power) integrated over this plane (for power normal to the plane, obviously) will give you the square of S11.
I'm not sure what you mean. Short both sides of what?
i am attaching one image of the arrangement here. by short i meant that i have to short the both ends of the structure as i want the reflection profile.

Any surface, really -- a square sheet should do. For best results, surface normal in the direction of propagation, and the sheet completely covers the cross-sectional area of the waveguide.
I'm not sure what you're expecting to get out of this test, though. Won't the power always be completely reflected?
