Multiscale Methods for Engineering Double Negative Metamaterials
نویسندگان
چکیده
The approach taken here solves the Maxwell equations inside metamaterial crystals directly and explicitly with no approximations made. The Bloch wave solution and dispersion relation is given by a power series in the ratio between wave number and period. Each term is iteratively defined by the solution of an auxiliary problem depending on the configuration and shapes of the scatterers. The leading order term in the power series for the dispersion relation is given by the complex effective index of refraction. The effective properties and their resonance frequencies depend explicitly on the shape of the scatterers. Double negative behavior is explicitly controlled by the location of resonance frequencies related to spectra intrinsic to the geometric configuration of the multi-phase inclusions. This provides for the rational shape design of inclusions for control of double negative behavior across prescribed frequency ranges.

A Review of Metamaterials and its Applications
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...

Following our recent theoretical development of the concept of nano-inductors, nano-capacitors and nanoresistors at optical frequencies and the possibility of synthesizing more complex nanoscale circuits, here we theoretically investigate in detail the problem of optical nano-transmission lines (NTL) that can be envisioned by properly joining together arrays of these basic nano-scale circuit el...
متن کاملStudy of anomalous wave propagation and reflection in semi-infinite elastic metamaterials
Elastic metamaterials have been investigated to achieve negative effective properties, which cannot be found in the conventional elastic medium. In this paper, planewave propagation and reflection in semi-infinite elastic metamaterials with doubly or triply negative material properties are studied analytically and numerically. The unique negative refractions for the longitudinal (P) wave and tr...
