Abstract :
In order to obtain a solution of a canonical problem in closed form, a planar structure is considered. The first part of the structure is an infinitesimally thin perfectly conducting halfplane, while the second one consists of a wire-mesh halfplane. The wire mesh is described by the equivalent sheet impedance operator, derived by K.F. Casey (1981), which is valid when the mesh dimensions are small in comparison with the wavelength. The diffraction of an obliquely incident plane wave is studied by means of a Wiener-Hopf technique. The cases of transverse-electric and transverse-magnetic incidence are considered.<>
