Diffraction by a strongly elongated object illuminated by an electromagnetic plane wave propagating in the paraxial direction -- application to a prolate ellipsoid

Following the asymptotic theory of creeping waves on a strongly elongated object, developed by Andronov and Bouche [1], the authors have derived explicit formulas for the asymptotic currents on a strongly elongated object excited by an electromagnetic plane wave propagating in the paraxial direction. Numerical results for the asymptotic currents along the geodesics followed by the creeping waves will be shown and compared to the results obtained by solving the EFIE.
