摘要
The leading term for the scattering diagram, in the scalar problem concerning the diffraction of a plane wave by a narrow circular impedance cane, is obtained. Although, up to now, the problem cannot be solved in an explicit form, its reduction to a non-oscillating integral equation has been recently developed. It is used here in order to determine formal asymptotics of the scattering diagram by means of a perturbation method.
