Abstract
The scattering of propagating waves from an abruptly terminated single-mode-fiber waveguide is investigated analytically by means of an integral equation. Weak-guidance conditions on the fiber guide are assumed to formulate the corresponding boundary value problem, and then a Neumann-series iterative solution is developed to solve the basic integral equation. The reflection coefficients of the propagating waves and the radiation patterns of the diffracted waves are also computed. Numerical results are presented for several abruptly terminated fiber guides.
