In a periodic arrangement of equally-doped graphene monolayers the electromagnetic wave propagation is described by band theory. We have found that the photonic response of this system enriches when the doping level is sequentially-modulated acquirin

Plasmonic bands in 1D graphene-based photonic crystals have recently been reported for transverse magnetic polarization in the low THz regime. In this work, we demonstrate that plasmon coupling, giving rise to plasmonic bands, is also present for tra

In this work, we propose a two-dimensional photonic crystal–photonic crystal heterostructure that possesses the requirements for exciting an electromagnetic interface mode and investigate its interaction with photonic crystal waveguide modes. To st

In this work, we demonstrate the existence of TE polarized surface Bloch modes localized at the boundary of semi-infinite graphene-based photonic crystal and homogeneous dielectric. Imposing an alternate low-high doping level on graphene layers along

We have calculated the photonic bands of a dispersive and lossy periodic array of left-handed metamaterial layers in air. Depending on the behavior of the flelds inside the metamaterial component, two categories of modes for oblique propagation are i

Theoretical and experimental results for flexural waves of a rectangular plate with free ends are obtained. Both the natural frequencies and mode shapes are analyzed for the lower normal modes. To take into account the boundary conditions, a plane wa

We have studied theoretically the photonic bands in a periodic dielectric–metallic superlattice. In the calculations the absorption in the metallic layers was taken into account using the well-known Drude model for the dielectric function, e ( ω )

Influences of perturbative disorders to the photonic properties of one-dimensional periodic dielectric/metal superlattices have been numerically studied. In the calculations, two different disorders were considered, i.e. the disorder in position and

We studied the transit time of a narrow Gaussian wave packet that traverses a metallic layer of plasma frequency ωp. The wave packet can be constructed with the mid-frequency ωo lying below, above or just at ωp. We found that the transmitted packe

One-dimensional photonic crystals are analyzed by using symmetric periodic multilayers to determine an equivalent dielectric function associated to these systems. This equivalent dielectric function has the characteristic shape of those dielectric ma
