摘要

我们用Floquet-Bloch (FB)法和Nicolson-Ross-Weir (NRW)法分别对介电和磁介电布拉格叠加的介电常数和磁介电率进行了提取和比较。虽然提取的传播常数相同，但波阻抗不同。此外，NRW方法产生了介电布拉格堆栈的磁效应，而FB方法给出了期望的真空磁导率，也在带隙中。

Floquet-Bloch vs. Nicolson-Ross-Weir extraction for magneto-dielectric Bragg stacks

We extract and compare the permittivity and permeability from a dielectric and a magneto-dielectric Bragg stack with the Floquet-Bloch (FB) method for the infinite stack and the Nicolson-Ross-Weir (NRW) method for the finite stack. While the extracted propagation constants are identical, the wave impedances are different. Moreover, the NRW method yields magnetic effects for the dielectric Bragg stack, while the FB method gives the expected vacuum permeability, also in the bandgab.
