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 کاملLosses in left-handed materials.
Interest in negative refractive index, or left-handed (LH) materials, has escalated rapidly over the last few years and it now appears that useful LH materials may be realizable in the microwave region. However there is also considerable interest in LH materials for infrared and visible applications. The purpose of this paper is to explore the limitations of LH materials at short wavelengths du...
متن کاملEffective medium theory of left-handed materials.
We analyze the transmission and reflection data obtained through transfer matrix calculations on metamaterials of finite lengths, to determine their effective permittivity epsilon and permeability micro. Our study concerns metamaterial structures composed of periodic arrangements of wires, cut wires, split ring resonators (SRRs), closed SRRs, and both wires and SRRs. We find that the SRRs have ...
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 کاملPhase compensating effect in left-handed materials
Based on the difference between negative refraction and negative refractive index, the phase compensating effect was proposed to distinguish negative refraction in left-handed materials (LHMs) and photonic crystals (PCs). With this effect, perfect lens (PL) of LHM in which both propagating and evanescent waves contribute to the image could be well understood, which is differed from superlens ma...
