Superconducting metamaterials [PDF]
Physics Reports, 2018 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

Journal of Optics, 2010 Optical space in metamaterials may be engineered to mimic the landscape of a multidimensional Universe which has regions of different topology and different effective dimensionality. The "metamaterial landscape" may include regions in which one or two spatial dimensions are compactified.

Towards three-dimensional optical metamaterials
Nano Convergence, 2017 Metamaterials have opened up the possibility of unprecedented and fascinating concepts and applications in optics and photonics. Examples include negative refraction, perfect lenses, cloaking, perfect absorbers, and so on.

Superconducting metamaterials [PDF]
Applied Physics Letters, 2005 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.

Topological Insulator Metamaterials
Chemical Reviews, 2023 Confinement of electromagnetic fields at the subwavelength scale via metamaterial paradigms is an established method to engineer light-matter interaction in most common material systems, from insulators to semiconductors, from metals to superconductors.

SIMULATIONS OF THE PROPERTIES OF ELONGATED HEXAGONAL DODECAHEDRON SYSTEMS
TASK Quarterly, 2014 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

Optical nonreciprocity via transmissive time-modulated metasurfaces
Nanophotonics, 2022 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

CORE-SHELL MODELLING OF AUXETIC INORGANIC MATERIALS
TASK Quarterly, 2014 This paper investigates the suitability of the General Utility Lattice Program (GULP) for studying auxetic materials at the molecular level. GULP is a force-field based molecular modelling package which incorporates the ‘core-shell’ model for simulating

Increasing the stability margins using multi-pattern metasails and multi-modal laser beams
Scientific Reports, 2022 Laser-driven metasails can enable reaching velocities far beyond the chemically propelled spacecrafts, which accounts for precise engineering of the acceleration and the stability degree of the lightsail across the Doppler-broadened band.
