Scattering of obliquely incident waves by inhomogeneous fibers

Abstract

The problem of the interaction of obliquely incident electromagnetic waves with a radially inhomogeneous fiber cylinder is treated analytically. By formulating this problem in terms of the two‐point boundary‐value problem, we eliminate the need to evaluate untabulated functions or to invert large matrices. Numerical results for the differential scattering cross sections are obtained for the case of an inhomogeneous fiber whose radial dielectric variation may be described by the Luneberg profile. It is found that the induced cross‐polarized scattered field as well as the characteristics of the total scattered fields are influenced significantly by the inhomogeneity of the dielectric medium.
