exciting a cylinder with plane wave

[r.bahl]

Hi everyone
i have to excite a cylinder (in HFSS ) using a plane wave and analyze the E filed at the interface of the cylinder and the background. how do i make the set-up of the system . I mean , how do i set up the boundary conditions ( is there a need to set up the boundary conditions? ) and the plane wave excitation zero phase point relative to each other ?
Any kind of help will be highly acknowledged
Thanx in advance

Guys this is really important for me ... kindly guide me ....
pls tell me how and what kind of boundary conditions shall i use in simulating a scattering of plane wave by a dielectric cylinder ... any kind of help would be highly acknowledged ..thanx
