Simple integral equations for twodimensional scattering with further reduction in unknowns
Abstract
A simple set of integral equations with reduced unknowns and kernel singularity are derived for simulating arbitrarilyshaped twodimensional inhomogeneous composite scatterers. By utilizing a known equivalence between electric and magnetic currents, new equivalent currents are introduced with the resultant integral formulation exhibiting a volume integral in addition to a surface integral, each in terms of a single equivalent current component. A pulse basispoint matching moment method implementation of the reduced unknown integral equations is presented. Scattering patterns computed with the numerical code are compared with results obtained via alternative analytical techniques.
