Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

Abstract The terahertz (0.1–10 THz) range represents a fast-evolving research and industrial
field. The great interest for this portion of the electromagnetic spectrum, which lies between …

A broadband absorption and polarization conversion switchable terahertz metamaterial
device can be obtained by introducing vanadium dioxide with the metal to insulate phase …

Hybrid metamaterials that exhibit reconfigurable responses under external stimulus, such as
electric fields and light radiation, have only recently been demonstrated by combining active …

Although phase transitions have long been a centerpiece of condensed matter materials
science studies, a number of recent efforts focus on potentially exploiting the resulting …

An actively tunable broadband terahertz absorber is numerically demonstrated, which
consists of four identical vanadium dioxide (VO_2) square loops and a metal ground plane …

In this paper, we propose and demonstrate a switchable terahertz metamaterial absorber
with broadband and multi-band absorption based on a simple configuration of graphene …

Despite the exotic material properties that have been demonstrated to date, practical
examples of versatile metamaterials remain exceedingly rare. The concept of metadevices …

Unlike conventional optics, plasmonics enables unrivaled concentration of optical energy
well beyond the diffraction limit of light. However, a significant part of this energy is …

Chiral media exhibit optical activity, which manifests itself as differential retardation and
attenuation of circularly polarized electromagnetic waves of opposite handedness. This …
