Many natural shapes are chiral (or handed). Our hands, for example, have a righthand version and a left-hand version, the two types being mirror images of each other. Molecules are also classi ed according to their chirality, which determines their chemical characteristics. Glucose, for example, is sweet only in one chirality, while it is tasteless in the other. The notion of chirality for two ...

During the past ten years, a great interest in the research of metamaterials has been observed. Metamaterials are artificially invented materials that show the properties which are not detected in naturally occurring materials. Metamaterials exhibits negative permittivity and/ or negative permeability. This paper presents a review of different types of metamaterials, their own unique properties...

BACKGROUND AND PURPOSE Amygdalar and hippocampal volume measurements indicate a right-greater-than-left asymmetry for right-handed normal participants in most studies. The purpose of this study was to compare amygdalar and hippocampal volume ratios between right- and left-handed participants. METHODS Amygdalar and hippocampal volume measurements were performed in 34 (20 right-handed and 14 le...

The prevalent modern suggestion that Alexander the Great was left-handed probably derives from Michael Barsley's (1966) book, Left-handed man is a right-handed word, perhaps by mutation from as earlier story cited by Wile in 1934 from a 17th century Rabbirical exegesis, which said that Alexander discovered a country where all the inhabitants were left-handed. That itself may derive in part from...

left-handed (two-component) neutrinos νe, νμ, and ντ with the left-handed fields se, sμ, and sτ that are the charge conjugates of the right-handed neutrino fields νre, νrμ, νrτ , i.e., se = −iσ2 ν∗ re = (ν† re2,−ν re1), etc. The six left-handed neutrino fields form a six-vector, N = (νe, νμ, ντ , se, sμ, sτ ). The only mass term available for two left-handed neutrino fields Ni and Nj isMij (Ni1...

Coupling phenomena between artificial left-handed ~LH! transmission lines are explored on the basis of a transmission line approach of LH materials. A LH forward coupler in the form of an ideal lumped-element ladder network is presented and is shown to exhibit strong forward coupling that increases with decreasing of frequency. A quasi-lumped element microstrip implementation of a LH coupler is...

The sensitivity of planar waveguide sensor containing dielectric, superconductor, and left-handed materials has been theoretically investigated. The proposed waveguide sensor in this study consists of a metamaterial film bounded by a dielectric cover and a superconductor substrate. The variation of the sensor sensitivity are found to be strongly depended on the metamaterial film, the film thick...

The achiral liquid crystalline materials showing two B4 (HN) phases have been found to exhibit strong gelation ability for various organic solvents with reversible sol-gel phase transition. The gel is formed by helical tubules, which build entangled 3D network, encapsulating the solvent. The equilibrium of left- and right-handed tubules is preserved in the gel, even if the chiral solvent is used.

The set of realizable refractive indices as a function of frequency is considered. For passive media we give bounds for the refractive index variation in a finite bandwidth. Special attention is given to the loss and index variation in the case of left-handed materials.
