High-frequency diffraction by an elliptic cylinder: the far field

Abstract

In this work, we derive the asymptotics of the far field in the directions of forward and backward sectors for near-axial scattering, on the basis of the asymptotic formulas for the induced currents on the surface of a perfectly conducting elliptic cylinder with strongly elongated cross-section.
