A unified theory of thin material wires
Abstract
The author presents an integral equation and method of moments (MM) solution to the problem of scattering by a thin material wire of circular cross section. In general the material wire has permittivity and permeability different from those of free space. The wire of radius a must be sufficiently thin so that k sub 0 a is much less than 1, where k sub 0 is the free space wavenumber. However, there is no restriction on the absolute value of k(a), where k is the wavenumber in the material wire. The method is referred to as unified in that it applies to thin material wires of arbitrary complex permittivity and permeability. Thus, a single or unified formulation applies to a lowdensity dielectric/ferrite wire or to a highly conducting metallic wire.
