|Title:||Bulk-plasmon polaritons in metamaterial-metamaterial one-dimensional photonic superlattices|
de Carvalho, CAA
|Abstract:||We perform a theoretical study of the bulk-plasmon polaritons in one-dimensional photonic superlattices made up of alternate layers of different metamaterials with dispersive dielectric permittivities and magnetic permeabilities for both normal and oblique incidence. We demonstrate that for oblique incidence a finite projection along the growth direction of the electric or magnetic field of the incident wave associated with the transverse-magnetic or transverse-electric modes, respectively, leads to a coupling in each layer of the heterostructure of the photon modes with the bulk electric or magnetic metamaterial plasmons, respectively. Such photon-plasmon coupling gives rise to electric or magnetic longitudinal bulk-plasmon polariton bands in the photonic band structure of the metamaterial-metamaterial superlattice. We also analyze the conditions for suppression of the longitudinal bulk-plasmon polaritons in the photonic band structure and reflection spectra of such metamaterial-metamaterial heterostructures.
