我们将双尺度收敛方法应用于像PenRose拼贴这样的光子准周期结构的均匀化。这种收敛依赖于参数的无理性性质,该参数通过其相关的介电常数的切割和投影矩阵来表征准晶相:我们通过考虑高维空间中的周期结构来产生准晶。我们将该工具应用于向量麦克斯韦系统的齐次化。
We adapt two-scale convergence to the homogenization of photonic quasi-periodic structures such as Penrose tilings. This convergence relies upon the irrational nature of a parameter characterizing a quasi-crystalline phase through its associated cut-and-projection matrix of permittivity: We generate quasi crystals by considering a periodic structure in an upper-dimensional space. We apply this tool to the homogenization of the vector Maxwell system.
