ON THE SCATTERING AND THE MODIFICATION OF SCATTERING OF WAVES FROM A LONG WIRE,
Abstract
The problem of the scattering of waves by a long, thin metallic wire is studied. The Wiener-Hopf technique is used to solve the resulting integral equation. In Part I of this report, the case of a plane wave, with arbitrary angle of incidence, impinging upon an unloaded wire is considered. Explicit and rather simple expressions for the induced current, the far field pattern and the back-scattering cross sections are obtained. Numerical results are in reasonable agreement with existing experimental data. The modification of the scattering of normally incident plane waves by a loaded wire is investigated in Part II. The result shows that for short wires, the back-scattering cross sections may be modified effectively by central impedance loading, while for long wires, the modification is rather difficult to achieve. To nullify the back-scattering cross section, it is necessary to use active loading, if kh > 3.6. A physical explanation is also presented. (Author)
