Traditionally,“metamaterials” have been described by effective medium parameters due to
the subwavelength nature of unit particles. The continuous nature of medium parameters …

As a digital version of metamaterials, coding and programmable metamaterials have
experienced rapid development since they were initially proposed in 2014. Unlike …

Multiple-frequency-band metamaterial absorbers possess great application prospects,
which are usually achieved by vertically stacking or coplanar arranging several sub …

A dual-band terahertz metamaterial absorber composed of two identical square metallic
patches and an insulating medium layer on top of a continuous metallic ground is …

This paper presents a multi-band terahertz superabsorber with a surface structure that
consists of a square metallic patch with a very small rectangular hole whose area is only …

Various kinds of structure designs have been proposed to achieve the multiple-band
metamaterial absorbers. However, the discrete distance of adjacent frequencies of multiple …

A new type of quad-band terahertz metamaterial absorber based on a common sandwich
structure is investigated. In sharp contrast to the most previous studies focused on only …

Synthetic fractals inherently carry spatially encoded frequency information that renders them
as an ideal candidate for broadband optical structures. Nowhere is this more true than in the …

It is quite urgent to obtain multiple-band light absorbers because they are of great important
in many technology related fields. However, the realization of them is typically based on a …

In this work, a three-dimensional (3D) porous MXene/GO foam (MGOF) was successfully
synthesized and exhibited an excellent terahertz stealth property covering a whole …
