抽象。采用高阶等参元的边界元法可以模拟由电场积分方程给出的散射问题。本文描述了实现，并提供了惊人的数值证据的高阶收敛速度的近似的表面电流。一个关键问题是高阶几何近似的必要性，这导致了一些网格相关的变阶近似的极端效率。
Abstract. A boundary element method with higher order isoparametric elements allows for the simulation of scattering problems given by the electric field integral equation. This paper describes the implementation and provides striking numerical evidence of the higher order convergence rates for the approximation of the electric surface current. One key issue is the necessity of higher order geometrical approximation which leads to an extreme efficiency of some mesh-dependent variable-order approximation.
