“…The bandwidth and central frequency of each resonance change with the number of the periods. The finite thickness or termination of photonic crystals (PhCs) has a significant impact on the dispersive properties of the structure [5]- [7] and hence affects transmission properties. In particular, the transmission coefficient of a plane wave having frequency within the pass band exhibits a thicknessdependent periodic oscillation.…”

Under certain conditions, a transparent photonic band can be designed into a onedimensional metallodielectric nanofilm structure. Unlike conventional pass bands in photonic crystals, where the finite thickness of the structure affects the transmission of electromagnetic fields having frequency within the pass band, the properties of the transparent band are almost unaffected by the finite thickness of the structure. In other words, an incident field at a frequency within the transparent band exhibits 100% transmission independent of the number of periods of the structure. The transparent photonic band corresponds to excitation of pure eigenstate modes across the entire Bloch band in structures possessing mirror symmetry. The conditions to create these modes 1 and thereby to lead to a totally transparent band phenomenon are discussed.

“…The miniband width depends on the coupling strength, and thus on N . One of the most important properties of CRS is that the dispersion relation and transmission spectrum for a moderate number of unit cells of the superlattice can be optimized to closely approximate that of the infinite CRS [24,25]. As a result, the transmission phase via a finite-size CRS exhibits a smooth increase through a finite and high transmission miniband summing up to a total phase shift equal to the number of half-wave defects in the structure multiplied by π [25].…”

Due to their large electrical conductivity, stand-alone metallic films are highly reflective at microwave frequencies. For this reason, it is nearly impossible to observe Faraday rotation in ferromagnetic metal layers, even in films just tens of nanometers thick. Here, we show using numerical simulations that a stack of cobalt nano-layers interlaced between dielectric layers can become highly transmissive and display a large Faraday rotation and extreme directionality. A 45-degree Faraday rotation commonly used in microwave isolators can be achieved with ferromagnetic metallic layers as thin as tens of nanometers.

“…In most studies of CROWs performed to date infinite periodic structures composed of identical resonators have been considered. It should be noted that practical CROWs are always of finite size, and thus their characteristics can differ from those theoretically predicted for infinite structures [23]. O understanding how disorder in either the resonators size or the inter-resonator coupling coefficients affects CROW transmission characteristics has been primarily focused on the estimation of CROW fabrication tolerances [13,24].…”
