Electromagnetic radiation in the terahertz (THz) frequency range is a fascinating
spectroscopic tool that provides resonant access to fundamental modes, including the …

Despite the rapid development in the past years, performances of the perovskite solar cell
are still limited by the photovoltage and fill factor that are mainly determined by the charge …

Direct phase modulation is one of the most urgent and difficult issues in the terahertz
research area. Here, we propose a new method employing a two-dimensional electron gas …

The impedance matching to free space in metamaterial perfect absorbers has been believed
to involve and rely on magnetic resonant response, with direct evidence provided by the anti …

Terahertz (THz) radiation attracted great interest in the fields of material characterization,
nondestructive security screening, clinical diagnostics, and identification of chemicals and …

Strong optical pulses at mid-infrared and terahertz frequencies have recently emerged as
powerful tools to manipulate and control the solid state and especially complex condensed …

We have wrapped metallic cylinders with strongly absorbing metamaterials. These resonant
structures, which are patterned on flexible substrates, smoothly coat the cylinder and give it …

We present the design, numerical simulations and experimental measurements of terahertz
metamaterial absorbers with a broad and flat absorption top over a wide incidence angle …

Arbitrary control of terahertz (THz) waves remains a significant challenge although it
promises many important applications. Here, a method to tailor the reflection and scattering …

We demonstrate a graphene-based electro-absorption modulator achieving extraordinary
control of terahertz reflectance. By concentrating the electric field intensity in an active layer …
