我们提出了轮廓积分法（CIM）的扩展，用于处理平面波激励的圆形夹杂物的二维散射问题。 CIM 是一种解决平面问题的积分方程方法，通过对圆形散射体进行半解析处理可以大大提高其效率。它与边界元法（BEM）相关，并显示出有前景的域分解能力。通过研究介电棒阵列的散射，将性能和精度与全波有限积分技术 (FIT) 进行比较。
We present an extension to the contour integral method (CIM) for the treatment of two-dimensional scattering problems from circular inclusions with plane wave excitation. CIM is an integral equation approach to planar problems whose efficiency can be greatly enhanced by semi-analytical treatment of circular scatterers. It is related to the boundary element method (BEM) and shows promising domain decomposition capabilities. The performance and accuracy is compared to the full-wave finite integral technique (FIT) by studying the scattering of an array of dielectric rods.
