Scattering of plane waves and Gaussian beams by a screen with small opening is considered. The asymptotics far from the obstacle is obtained. The results can be useful for description of perforated nanolayers and for fitting the model based on the operator extensions theory.

Keywords: scattering, Green’s function, asymptotics.
