A simple and effective approach is presented for analyzing the plane‐wave scattering from nonplanar wire meshes. In contrast to both traditional integral equation solutions and homogenization techniques, which have a limited range of application in terms of the size of the unit cell, the present technique is applicable to structures with periodicities varying from a small fraction of the wavelength (e.g., 10 −10 λ 0 ) up to several wavelengths. The technique is applied to the analysis of meshes consisting of straight wires as well as wire meshes containing helical elements.
