Surface polaritons of a left-handed material slab
The dispersion relations of the surface polaritons of a slab made of a material which has dispersive permittivity and permeability, and is left-handed over a frequency band in the microwave range of several GHz, are investigated. Four branches of p polarized surface polaritons and two branches of s polarized ones are found to exist. The possibility of experimentally observing the surface polari...
متن کاملNonlinear Surface Plasmon Polaritons at the Interfaces Between Isotropic Media and Anisotropic Left-Handed Materials
Linear and nonlinear surface plasmon polaritons propagating along the interfaces between isotropic media and uniaxially anisotropic left-handed materials are investigated. A transition layer sandwiched between the connected media is described using a model of a two-dimensional gas of semiconductor quantum dots. The conditions of the existence of surface TM-modes when the components of the permi...
متن کاملLeft-handed interfaces for electromagnetic surface waves.
We show that surface electromagnetic waves (SEMWs) propagating along two-dimensional (2D) interfaces separating different metamaterials can behave analogously to 3D electromagnetic waves in either usual or left-handed media, depending on the permeabilities and/or permittivities of the two materials forming the interface. We derive the conditions when SEMWs carry energy opposite to the phase vel...
متن کاملNonlinear surface waves in left-handed materials.
We study both linear and nonlinear surface waves localized at the interface separating a left-handed (LH) medium (i.e., a medium with both negative dielectric permittivity and negative magnetic permeability) and a conventional [or right-handed (RH)] dielectric medium. We demonstrate that the interface can support both TE- and TM-polarized surface waves-surface polaritons, and we study their pro...
متن کاملInfrared surface polaritons on antimony.
The semimetal antimony, with a plasma frequency ~80 times less than that of gold, is potentially useful as a host for infrared surface polaritons (SPs). Relevant IR SP properties, including the frequency-dependent propagation length and penetration depths for fields into the media on either side of the interface, were determined from optical constants measured on optically-thick thermally-evapo...
