Bloch oscillations in chirped layered structures with metamaterials.
We analyze the Bloch oscillations of electromagnetic waves in chirped layered structures with alternating layers of negative-index metamaterial and conventional dielectric under the condition of the zero average refractive index. We consider the case when the chirp is introduced by varying the thickness of the layers linearly across the structure. We demonstrate that such structures can support...

متن کاملNonlinear Tamm states in layered metaldielectric metamaterials
Surface modes appear as a special type of waves localized near an interface separating two different media. In optics, linear electromagnetic surface waves are known to exist at an interface separating homogeneous and periodic dielectric media [1] as well as in layered structures containing thin metal films [2–4]. The interest in the study of nonlinear electromagnetic surface waves has been ren...

متن کاملEngineering the point spread function of layered metamaterials
Layered metal-dielectric metamaterials have filtering properties both in the frequency domain and in the spatial frequency domain. Engineering their spatial filtering response is a way of designing structures with specific diffraction properties for such applications as sub-diffraction imaging, supercollimation, or optical signal processing at the nanoscale. In this paper we review the recent p...
