A Thin Dielectric Sheet (TDS) Integral Equation Method Based on NURBS Surfaces

This paper presents a thin dielectric sheet (TDS) integral equation method with non-uniform rational B-spline (NURBS) surface modeling for the scattering analysis of three-dimensional thin targets. The NURBS surface can control the target’s geometry, which enabled a degree of freedom to design and optimize the electromagnetic characteristics of thin dielectric sheets. At last, a numerical example is presented to show the accuracy and efficiency of this method.
