Scattering of electromagnetic waves by cylinders coated with a radially inhomogeneous layer is addressed in this paper. Approximate solutions are obtained using two approaches to solve the electromagnetic wave equations. The first approach is a finite-difference solution of the equations. The second approach is to discretize the inhomogeneous layer and apply a close-form solution for cylinders coated with multiple homogeneous layers. The two approximate solutions are used to obtain the scattering and extinction efficiencies of three fibers having different coatings. The efficiency results and computing time required are compared in order to judge the relative merits of the two approximate solutions.
