Spline Boundary Element Solution of Dielectric Scattering Problems

Summarizes the methodology of the high-order boundary element method, using cubic spline interpolants for the source distribution and arbitrary surface shape, in the context of two-dimensional time-harmonic scattering problems. The high accuracy and efficiency attained are indicated. Extensions to three dimensional problems are referenced. The paper presents application and results in a circular cylinder. A square dielectric cylinder problem, with singularities at corners, is discussed.
