Aerogels with negative parameters have become a research hotspot since the discovery of
negative Poisson's ratio and negative thermal expansion coefficient in aerogels. The …

Metamaterials have been in research limelight for the last few years owing to the exotic
electromagnetic features these exhibit. With certain combinational forms of the design, these …

As one of the most versatile elements, carbon materials occupy the most plentiful allotropies
composed of pure or mixed hybridization orbitals of sp1/sp2/sp3. The design and synthesis …

The mechanism of negative permittivity/permeability is still unclear in the random
metamaterials, where the precise control of microstructure and electromagnetic properties is …

Metacomposites with negative electromagnetic properties are promising candidates for thin-
film capacitors, wearable cloaks, and electromagnetic wave attenuation. In contrast to the …

Double negative materials (DNMs) with simultaneously negative permittivity and
permeability have attracted extensive attention worldwide in recent years because of their …

While metal or carbon materials served as conductive phase in fabricating metamaterials or
metacomposites have been widely investigated, MAX phases could provide alternative …

Biomass‐derived carbon materials (BCMs) are encountering the most flourishing moment
because of their versatile properties and wide potential applications. Numerous BCMs …

Metacomposites have been induced widespread concern in the realization of negative
permittivity. In this paper, composites with titanium nitride (TiN) particles homogeneously …

A new modified hexagonal design structure with broadband‐negative refractive index
metamaterial was proposed in this manuscript. The proposed structure was composed of …
