Analytic solutions of the integral equations for the current induced on a narrow conducting strip are obtained by two methods. One method follows from an expansion of the strip current in a series of Chebyshev polynomials while the other is based on a special power series expansion. In the former, Fourier-type coefficients, depending on integrals of the excitation, are derived while in the latter the coefficients depend upon derivatives of the excitation. From knowledge of the strip current simple expressions for the far-zone scattered field are derived. Explicit results are given for plane wave excitation. The solution methods apply to the equations for the narrow slot in a planar conducting screen.read more

TL;DR: In this article, a technique for synthesizing a resistive taper that generates desired bistatic scattering and backscattering patterns from a strip is outlined, which is checked by computing the surface current density and scattered fields of the tapered resistive strip using the integral equation formulation and comparing with the physical optics results.

General analysis of narrow strips and slots
C. Butler,Donald R. Wilton +1 more
TL;DR: In this article, the general problems of TE and TM-excited slots in screens and conducting strips whose widths are narrow relative to the wavelength are investigated, and solutions for both polarizations as products of series of Chebyshev polynomials and appropriate singular functions exhibiting the known edge condition are presented.
