SIMULATIONS OF THE PROPERTIES OF ELONGATED HEXAGONAL DODECAHEDRON SYSTEMS
This study considers a 3D basic unit-cell proposed for auxetic and non-auxetic foams namely the elongated hexagonal dodecahedron deforming through changes in angle between its ligaments (idealised hinging model). This structure was studied in detail for

Adaptive Multichannel Terahertz Communication by Space-Time Shared Aperture Metasurfaces
We propose a technique for adaptive multichannel communication in the low-terahertz frequency regime through simultaneous and independent multifrequency multibeam scanning via a single time-modulated metasurface consisting of graphene micro-patch ...

Optical nonreciprocity via transmissive time-modulated metasurfaces
The frequency mixing property of time-modulated metasurfaces, attributed to the well-known phenomenon of temporal photonic transition, has led to several exotic functionalities in the last lustrum. Based on this concept, we demonstrate the possibility of

Superconducting metamaterials [PDF]
Evanescent wave amplification has been predicted under the ideal condition that the index of refraction, n=−1+i0 precisely, but is difficult to observe in practice because current metamaterials suffer from high losses. We present experimental results on a metamaterial that employs superconducting Nb metals and low-loss dielectric materials.

Superconducting metamaterials [PDF]
Metamaterials (MMs), i.e. artificial media designed to achieve properties not available in natural materials, have been the focus of intense research during the last two decades. Many properties have been discovered and multiple designs have been devised that lead to multiple conceptual and practical applications. Superconducting MMs have the advantage

Multiband terahertz metamaterial perfect absorber for microorganisms detection
We report a multi-resonant terahertz (THz) metamaterial perfect absorber (MPA)-based biosensor in the working frequency range of $$0 - 3.8 THz$$ 0 - 3.8 T H z for sensing of microorganisms (such as fungi, yeast) and wheat pesticides. Nearly $$100\%$$ 100

Spatio-temporal characterization of ultrashort vector pulses
Ultrafast vectorially polarized pulses have found many applications in information and energy transfer owing mainly to the presence of strong longitudinal components and their space-polarization non-separability.
