SCATTERING BY AN ARBITRARY ARRAY OF PARALLEL WIRES,
Abstract
Equations were developed for the scattering pattern of an arbitrary array of parallel wires. The wires are assumed to be infinitely long, perfectly conducting, and very small in diameter in comparision with the wavelength. The incident wave is assumed to be TM with respect to the wire axis, but it may have normal or oblique incidence on the wires. The solution includes the interaction effects among all the wires. Computer programs are included along with numerical data for the currents induced in the wires in plane arrays, circular arrays, square arrays, and others. The far-field scattering patterns of these arrays are presented graphically. It is shown that if a sufficiently great number of wires is present the scattering pattern approaches that of a solid conducting cylinder of the same cross-section shape as the wire-grid array. In this connection, the theory may be applied to a shipboard situation in which a radiating element or an incoming plane wave illuminates the superstructure and the field distribution is thereby distorted.
