Fast numerical method of the second order of accuracy for solving the inverse scattering problem

O. V. Belai Institute of Automation and Electrometry, Siberian Branch of Russian Academy of Sciences, Novosibirsk Abstract: A method is proposed for the numerical solution of the inverse scattering problem formulated in the form of integral equations of the Gelfand–Levitan–Marchenko type. Approximation of integral equations is performed with the second order of accuracy, which leads… Read More »

Diffraction by a perfectly conducting strip grating

A. V. Nemykin, D. A. Shapiro Institute of Automation and Electrometry, Siberian Branch of Russian Academy of Sciences, Novosibirsk Abstract: The problem of scattering of an s-polarised wave by a periodic grating of thin ideally conducting strips at normal incidence is solved. The Riemann–Hilbert method is used to obtain an infinite system of equations for… Read More »
