利用格点和技术、聚合T矩阵算法和分层系统的广义反射矩阵和广义透射矩阵，提出了一种非常有效和精确的方法来描述平行圆柱周期阵列的二维电磁散射特性。该方法是相当普遍的，适用于各种配置的2-D周期阵列。阵列的单元可以包含两个或多个圆柱体，其可以是电介质、导体、回转介质或它们的不同尺寸的混合物。圆柱体沿着每个阵列平面的周期性间隔在所有层上应该相同，但是在其他方面，不同层中的圆柱体的材料特性和尺寸可能不同。数值算例验证了该方法的有效性和准确性。
A very efficient and accurate method to characterize two-dimensional (2-D) electromagnetic scattering from multilayered periodic arrays of parallel circular cylinders is presented, using the lattice sums technique, the aggregate T-matrix algorithm, and the generalized reflection and transmission matrices for a layered system. The method is quite general and applies to various configurations of 2-D periodic arrays. The unit cell of the array can contain two or more cylinders, which may be dielectric, conductor, gyrotropic medium, or their mixture with different sizes. The periodic spacing of cylinders along each array plane should be the same over all layers, but otherwise the cylinders in different layers may be different in material properties and dimensions. The numerical examples validate the usefulness and accuracy of the proposed method.
