Abstract

We present an expression for the electromagnetic-diffraction edge wave produced by a three-dimensional Gaussian beam at grazing incidence upon an absorbing circular cylinder whose radius is much greater than the wavelength. The good conductor and the perfect conductor are included as special cases. Moreover, the edge-wave expression is valid in the Fresnel region as well as in the far field.
