Scattering of Plane Waves by Joining Chiral Half-Sheets

The plane wave scattering excited by joining uniaxial chiral half-sheets is addressed in the high-frequencies domain. In particular, the propagation scenario consists of two half-sheets that are arranged in a planar junction bounded by free space. The propagation direction of incident plane waves is assumed to be arbitrary with respect to the linear discontinuity of the junction and therefore the scattering scenario is three dimensional. Reflection and transmission are formulated by using a bounce diagram technique accounting for the boundary conditions, whereas the uniform asymptotic physical optics approach is applied for evaluating the diffraction contribution due to the discontinuity. At the best authors’ knowledge, no further analytical procedures solving the problem are available in literature. Data resulting from a commercial electromagnetic solver are used as reference to test the value of the proposed method, and made available for validating other techniques.
