Nonlinear 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 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 کاملNovel Electromagnetic Radiation in Left - Handed Materials
In this thesis, Cerenkov radiation of a moving charged particle inside a Left-Handed material (LHM) is studied through both theory and numerical simulations. A LHM is a material whose permittivity and permeability have negative real parts. In the analysis of this thesis, the general theory of Cerenkov radiation was first studied for the unbounded regions filled with LHM. The physical meanings o...
متن کاملLeft-handed electromagnetic waves in materials with induced polarization and magnetization
We analyze the properties of electromagnetic waves inside materials with induced polarization and magnetization. We show that if the polarization and magnetization of the material are sufficiently large and appropriately phased, then the system supports the formation of left-handed waves. In some respects, such a system behaves similarly to materials with a negative index of refraction, yet the...
متن کاملReview of Electromagnetic Theory in Left-handed Materials
We reviewed the recent progress in the left-handed materials with simultaneously negative permittivity and permeability. Attention has been given to the fundamental electromagnetic properties in the left-handed material, metamaterial designs, applications, and homogenization methods.
