The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

Over the past 5 years, digital coding and programmable metamaterials have been
developed rapidly since their first exhibition in 2014. The iconic feature of the digital coding …

Metamaterials based on effective media can be used to produce a number of unusual
physical properties (for example, negative refraction and invisibility cloaking) because they …

The attenuation of low-frequency sound has been a challenging task because the intrinsic
dissipation of materials is inherently weak in this regime. Here we present a thin-film …

Because of their exceptional capability to tailor the effective medium parameters,
metamaterials have been widely used to control electromagnetic waves, which has led to …

Metamaterials, artificial composite structures with exotic material properties, have emerged
as a new frontier of science involving physics, material science, engineering and chemistry …

This review aims to summarise the progress in some materials and structures for
electromagnetic applications, such as microwave absorption, electric shielding and antenna …

Natural and human environments are abundant of unused renewable energy such as
mechanical energy, acoustic energy, electromagnetic energy, thermal energy, etc. The idea …

The field of metamaterials has opened landscapes of possibilities in basic science, and a
paradigm shift in the way we think about and design emergent material properties. In many …

We present the design, analysis and measurements of a polarization-insensitive tunable
metamaterial absorber with varactor diodes embedded between metamaterial units. The …
