On electromagnetic-wave scattering by a dielectric cylinder

Resumo

An approximate method that is analogous to the eikonal approximation in quantum scattering theory is developed to solve the problem оf the scattering of an electromagnetic wave in the case of its oblique incidence onto an infinite circular cylinder. The limits of applicability of the method include, in particular, the X-ray range. It is shown that inclusion of the finiteness of the cylinder thickness leads to significant asymmetry of the angular distribution of the scattered radiation. The results can be used to improve the kinetic theory of radiation propagation in a system of parallel fibers.
