Numerical Solution for the Problem of Electromagnetic Scattering by a Thin Finite Conducting L-Shape Fiber

Abstract

Scattering by a thin L-shape finite conducting fiber is computed numerically at normal incidence for an incident wave whose electric field vector is parallel to one leg (driven leg) and perpendicular to the other (undriven leg). The moment method via a point matching scheme was used. This seems to represent the first solution of the coupled Pocklington integro-differential equations for the L-shape finite conducting fiber. The solution satisfies the boundary conditions of the problem and the results of this paper show that a current is induced in the undriven leg of the fiber. The scattering cross section is then obtained and compared to that of the same length straight finite conducting fiber parallel to the incident electric field [1].
