Conducting Strip

An integral equation for the singular currents on a conducting strip illuminated normally by a plane electromagnetic wave polarized parallel to the strip is obtained and the singularities of the currents are treated by using a conformal transformation. The integral equation is then solved numerically by a Fourier analysis of the resulting unknown but regular function, and the computed results for the induced currents on the strip are presented.

Conducting Strip

The diffraction of a plane electromagnetic wave by an infinitely long, unidirectionally conducting strip is formulated as a Wiener–Hopf integral equation and is solved asymptotically for a wide strip by transform techniques. In addition to the diffracted fields produced by a perfectly conducting strip, surface-wave excitation and scattering at the edges and interaction between the ends of the lines of conductivity appear in the solution. These effects are illustrated by numerical results of the scattering cross section at normal incidence for various directions of conductivity.

Total Scattering Cross Section

The scattering of a plane electromagnetic wave of wave number k by a uni-directionally conducting infinite strip of width 2a is investigated, The problem is formulated in terms of an integral equation whose solution is obtained by a well-known procedure in the form of a series in powers of ka. Expressions for the far-zone fields and the first two terms in the series for the total scattering cross section are obtained.
