Abstract

Phenomena of coupling of wave beam and surface wave at impedance rod with spatially oscillating parameters are theoretically considered. Used method is asymptotic with respect to smoothness parameter and is numerical with respect to perturbation amplitudes. It combines advantages of the asymptotic and numeric methods in cases of quasiperiodic structures with large number of “periods”. Obtained coupling coefficients are compared with known asymptotic expressions.
