Left-handed materials do not make a perfect lens.
By means of an analysis on evanescent waves in left-handed materials (LHM), we show that within a slab of such a medium, sandwiched between two positive refraction media, there is amplification of evanescent waves in ideal lossless, dispersiveless media; however, contrary to previous claims, this is limited to a finite width of the slab so that it prevents their restoration and perfect focusing...
متن کاملComment on "Left-handed materials do not make a perfect lens".
In a recent Physical Review Letter [1] Garcia and Nieto Vesperinas (GNV) dispute the claim of perfect lensing made in [2]. GVN claim that the solutions proposed in [2] imply infinite energy density and are therefore inadmissible. They also claim that finite absorption leads to catastrophic collapse of the amplifying solutions vital to focussing. GNV calculate in equation (6) of their Letter the...

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 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...
