چکیده
Metamaterials are rationally designed composites made of building blocks which composed one or more constituent materials. Metamaterial properties can go beyond those the ingredient materials, both qualitatively and quantitatively. In addition, their be mapped on some generalized continuum model. We present general procedure designing elastic metamaterials based masses springs. show that using this simple approach we design any set effective including linear metamaterials,—defined by bulk modulus, shear mass density—and nonlinear metamaterials,—with instabilities programmable parts. designs corresponding numerical calculations to illustrate constitutive behavior. Finally, discuss addition a thermal stimulus mechanical metamaterials.

We analyze the transmission properties of double negative metamaterials (DNM). Numerical simulations, based on the transfer matrix algorithm, show that some portion of the electromagnetic wave changes its polarization inside the DNM structure. As the transmission properties depend strongly on the polarization, this complicates the interpretation of experimental and numerical data, both inside a...
متن کاملEffective Dynamic Properties and Multi-Resonant Design of Acoustic Metamaterials
In the study, a retrieval approach is extended to determine the effective dynamic properties of a finite multilayered acoustic metamaterial based on the theoretical reflection and transmission analysis. The accuracy of the method is verified through a comparison of wave dispersion curve predictions from the homogeneous effective medium and the exact solution. A multiresonant design is then sugg...
