Beam oscillations and curling in chirped periodic structures with metamaterials

Davoyan, Arthur; Sukhorukov, Andrey; Shadrivov, Ilya; Kivshar, Yuri


We study the propagation of electromagnetic waves in one-dimensional chirped periodic structures composed of alternating layers of negative-index or left-handed metamaterial and conventional dielectric, under the condition of the zero average refractive index. We consider the case when the periodic structure has a linear chirp, and the chirp is introduced by varying linearly the thickness of the layers across the structure. We apply an asymptotic analytical method for the analysis of the...[Show more]
