This process also affects the structure of the diffraction coefficient. A new diffracted field should be obtained for the illumination of cylindrical waves. This paper introduces a new diffraction coefficient for the impedance half-plane, fed by cylindrical waves. The total and total geometric optics waves are also derived. The variation of the fields is studied numerically.eninfo:eu-repo/semantics/closedAccessImpedance SurfaceDiffraction TheoryDiffraction CoefficientArticle10.1016/j.ijleo.2019.01.0972-s2.0-85060853126
