Abstract :
A rod with nonperiodically oscillated perturbation of surface impedance is considered. The Krylov-Bogoliubov-Mitropolsky asymptotic method is used for solving boundary-value problem describing electromagnetic wave propagation in the open waveguiding structure. Mutual transformation of a wave beam falling onto inhomogeneous impedance rod and surface wave propagating along this rod is investigated. Analytical solutions for some particular cases are obtained.
