Dispersion regions overlapping for bulk and surface polaritons in a magnetic-semiconductor superlattice

Dispersion relation for surface plasmon polaritons on a Schottky junction.

The conventional analysis of surface plasmon modes on dielectric-metal interfaces requires clearly defining the permittivity discontinuity at the interface. A pivotal assumption of such an analysis is that the formation of the dielectric-metal interface does not change the material properties and the materials forming the interface have identical permittivities before and after the formation of...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...

Experimental demonstration of surface and bulk plasmon polaritons in hypergratings

Hyperbolic metamaterials (HMMs) represent a novel class of fascinating anisotropic plasmonic materials, supporting highly confined bulk plasmon polaritons in addition to the surface plasmon polaritons. However, it is very challenging to tailor and excite those modes at optical frequencies using prism coupling technique because of the intrinsic difficulties to engineer non-traditional optical pr...

Surface and Bulk Plasmon-polaritons in Periodic Metallic Heterostructures

We have investigated the theory of the plasmon-plariton niodes of a pr iodic metallic heterostructure d i n g use of a local theory. A rich spectrum is found of b t h buU: and surface excitations whose freguency depends upon the dielectric properties of each constituent. We discuss the connections of our analysis with the results obtained within a non-local theory and the effects of retardation...
