Abstract :
This paper extends the path deformation method to a new 3D case. That is, the parabolic surface with polygonal contour. This technique was first presented for another case (parabolic surface with circular contour) in the EUCAP 2006 conference (Vico, 2006). It was awarded as best paper of antennas in the conference. The technique is essentially the same, but the technical details are more complicated for this case.
