Effective 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 کاملNegative effective permeability and left-handed materials at optical frequencies.
We present here the design of nano-inclusions made of properly arranged collections of plasmonic metallic nano-particles that may exhibit a resonant magnetic dipole collective response in the visible domain. When such inclusions are embedded in a host medium, they may provide metamaterials with negative effective permeability at optical frequencies. We also show how the same inclusions may prov...
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.
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...
