نویسندگان
چکیده
In this paper, a novel cylindrical metamaterial exhibiting zero Poisson’s ratio in two different directions is introduced. Detailed CAD modelling of curved Fish-Cells necessary for numerical and experimental analysis are presented. High-fidelity finite element models developed to assess the homogenisation studies ratio, Young’s modulus torsion behaviour, demonstrating curvature effect independency mechanical behaviour from tessellation numbers. Experimental performed validate deformation fracture mechanism discussed simulations. Moreover, buckling modal behaviours metamaterials studied compared with equivalent shell models.

Metamaterials at zero frequency.
We investigate the problem of designing metamaterial structures which operate at very low frequencies. As an example, we consider the case of a DC magnetic cloak, which requires a variable, anisotropic magnetic permeability with both paramagnetic and diamagnetic components. We show that a structure based on superconducting components is the key to diamagnetism at low frequencies, and present a ...
متن کاملMicrostrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...
متن کاملTopological mechanics of gyroscopic metamaterials.
Topological mechanical metamaterials are artificial structures whose unusual properties are protected very much like their electronic and optical counterparts. Here, we present an experimental and theoretical study of an active metamaterial--composed of coupled gyroscopes on a lattice--that breaks time-reversal symmetry. The vibrational spectrum displays a sonic gap populated by topologically p...
متن کاملOn-chip zero-index metamaterials
Metamaterials with a refractive index of zero exhibit physical properties such as infinite phase velocity and wavelength. However, there is no way to implement these materials on a photonic chip, restricting the investigation and application of zero-index phenomena to simple shapes and small scales. We designed and fabricated an on-chip integrated metamaterial with a refractive index of zero in...
متن کاملMimicking celestial mechanics in metamaterials
Einstein’s general theory of relativity establishes equality between matter–energy density and the curvature of spacetime. As a result, light and matter follow natural paths in the inherent spacetime and may experience bending and trapping in a specific region of space. So far, the interaction of light and matter with curved spacetime has been predominantly studied theoretically and through ast...
