  • Abstract
    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.
