Second-order functional-difference equations. II: Scattering from a right-angled conductive wedge for \(E\)-polarization. (English) Zbl 1064.39017

The authors discuss a second-order difference equation with \(2\pi\)-periodic coefficients and with shift \(\pi\), which comes from the electromagnetic scattering by a right-angled magnetically conductive wedge. A rigorous procedure for constructing the general solution is proposed, and the particular case of no branch points is analysed. A high-frequency asymptotic expression for the electric field is presented, furthermore numerical results for the backscattering coefficient are proposed.
