Graphene is an ideal 2D material system bridging electronic and photonic devices. It also
breaks the fundamental speed and size limits by electronics and photonics, respectively …

Terahertz radiation refers to a broad electromagnetic spectrum range between microwave
and infrared waves, which is also known as the terahertz gap due to inadequate materials …

As the basis of a diverse set of photonic applications, such as hologram imaging,
polarization, and wave front manipulation, the local phase control of electromagnetic waves …

Electromagnetic metamaterials are designer materials made from 'artificial atoms' which
provide unprecedented control over light matter interactions. Metamaterials are fashioned to …

Recently, two rich and exciting research fields, layered two-dimensional (2D) materials and
metamaterials, have started overlapping. Metamaterials are artificial, engineered materials …

We report on a novel electrically tunable hybrid graphene-gold Fano resonator. The
proposed metamaterial consists of a square graphene patch and a square gold frame. The …

Graphene is a new material with a single-layer two-dimensional (2D) honeycomb lattice
structure. It has excellent optical, electrical and mechanical properties, and it is closely …

The terahertz (THz) region of the electromagnetic spectrum spans the gap between optics
and electronics and has historically suffered from a paucity of optoelectronic devices, in …

Split-ring resonators represent the ideal route to achieve optical control of the incident light
at THz frequencies. These subwavelength metamaterial elements exhibit broad resonances …

In this paper, we examine graphene as a material for reconfigurable terahertz (THz)
optoelectronics. The ability of electrically tuning its optical properties in a wide range of THz …
