High Frequency Asymptotic Evaluation for Electromagnetic Scattering from a Circular Conducting Cylinder -E Polarization-

In this paper, the scattering far-field from a circular conducting cylinder has been formulated for E polarization using physical optics (PO) approximation. Assuming the radius of the cylinder is electrically large, non-uniform and uniform asymptotic solutions are derived. While the former solution is found to be inaccurate near the forward direction, the later is valid for all observation direction. In order to check the validity of our formulation, various numerical calculations have been done and the results are compared with those by direct numerical integration.
