Abstract :
Phenomena of coupling of wave paraxial beam and quasisurface wave at perfectly conducting plane with segment of spatially oscillating surface impedance is considered. Integral equation for perturbed current distribution is obtained. Method of moments is used. Solution was expanded in terms of pseudoharmonic middle-domain (long subdomain) basis functions. Smooth envelopes in form of a combination of atomic functions and the Lagrangian interpolating polynomials were applied. Results for some types of test functions were compared.
