Abstract:

This investigation determines the induced currents on a finite sized array of parallel wires then illuminated by a plane wave with varying incidence angles by the method of moments. The arrays considered are of various spacings, lengths, and widths, ranging from 5 to 36 wires per wavelength, and one to two wavelengths in length. The effects of a ground plane parallel to the array, and located one quarter wavelength away, is also studied. The analysis is accomplished by the method of moments using piecewise sinusoidal expansion functions and Galerkins method. An algorithm is developed to accomplish the integration and matrix inversion. It was written general enough for the user to specify number of wires, number of segments, wire length, wire diameter, wire spacing, spacing above the ground plane, frequency, and magnitude of incident electric field. The results illustrate the various effects that changing the wire spacing, wire length, number of segments, and incidence angle have upon the induced current. The results are also compared to the modified physical optics approximation. The results of this investigation indicate that the moment method is accurate enough to produce very reasonable approximations of the induced current for most applications. Author
