Sentence examples for limits of metamaterials from inspiring English sources

The debate did highlight limits of metamaterials.

Although the λ/a relationship could tell us what size of unit we need and which method we should choose for the fabrication, it limits the application of metamaterials in the kHz and MHz frequency range, as the unit size would be on the order of 102 m, making the overall size of the metamaterial too large for practical application.

These include negative, near-zero, and indefinite permittivity or permeability indices; backward waves and backward phase matching in nonlinear optics; and potential applications of metamaterials for perfect absorption, cloaking, and imaging below the diffraction limit using super- and hyperlenses.

The fabrication of metamaterials with a 'designed' microstructure that exhibit a Poisson's ratio approaching the thermodynamic limits of 1/2 and −1 increases the likelihood of realising these phenomena for applications.

"It's all very, very fascinating," said Dr. Shalaev, describing the possibilities of metamaterials.

In reality, the device depends on a complex tangle of mathematical theory, a vast amount of computing power and the use of "metamaterials".

A class of metamaterials designed with low permittivity provides a platform for developing optical devices with unconventional properties.

The tunable dielectric and magnetic properties of metamaterials could be used in stealth technologies to cloak an object from view.

Two principal classes of metamaterials are treated: (1) metamaterials made of nematic liquid crystals containing nanoparticulates and (2) metamaterials made of nanostructures infiltrated with liquid crystals.

We make use of metamaterials for this energy harvesting technique.

Behind most cloaking ideas is the use of metamaterials - materials whose properties are purposefully designed, defined not by chemistry but by the materials' size, shape and structure.
