摘要

本文对不同电参数的复合双层结构的平面波散射进行了分析。该结构包括介电层和手性层，两者均由不同几何形状的贴片阵列加载。分析了不同载荷配置下的反射特性。该分析基于广义散射矩阵(GSM)。采用共轭梯度迭代法结合快速傅里叶变换(CG-FFT)求解各层界面导体上的BC问题，得到各层的散射矩阵。研究了所有的散射传播模式。结果表明，不同贴片构型的结构比方形贴片具有更好的吸收特性。

Minimizing of back-scattering using composite double layer structure of different patch configurations

The paper presents the analysis of plane wave scattering from composite double layer structures of different electrical parameters. The structure comprises dielectric and chiral layers and both are loaded by arrays of patches of different geometries. The reflection characteristics are analyzed for different loading configurations. The analysis is based on the generalized scattering matrix (GSM). The scattering matrix of each layer is obtained by solving the BC problem on the conductor at the interface of each layer using the conjugate gradient iteration scheme in conjunction with the fast Fourier transform (CG-FFT). All of the scattered propagated modes are studied. The results illustrate that the proposed structure with different patch configurations achieves better absorption characteristics than the use of square patches.
