Use of the generalized eikonal in the analytic solution of the problem of electromagnetic-wave diffraction by a 2D perfectly conducting half-plate

The method of the generalized eikonal is applied to obtain a general analytic solution to the problem of electromagnetic-wave diffraction by a 2D semi-infinite perfectly conducting scatterer with an open-polygon boundary. A specific solution is found for the problem of diffraction by a 2D perfectly conducting half-plate. Analytic formulas and calculation results are presented.
