In this study, the physical structure for the propagation of whistler waves in ducts of nonuniform cold plasma density is investigated by means of electrodynamics theory. Expressions for the solution of the field equations are determined analytically using perturbation technique, and power transmitted by modes is evaluated in terms of a parabolic model for the plasma density distribution. The set of eigenmodes and their spatial structure are analyzed and the dependencies of the eigenmode propagation properties on the duct characteristics are studied.
