Over the past three decades a new spectroscopic technique with unique possibilities has
emerged. Based on coherent and time‐resolved detection of the electric field of ultrashort …

We review pioneering and recent studies of the conductivity of solid state systems at
terahertz frequencies. A variety of theoretical formalisms that describe the terahertz …

A thermally tunable terahertz window based on the combination of a metamaterial and the
phase change material VO2 is proposed. The window is composed of two vanadium oxide …

Tunable terahertz (THz) functional devices have exhibited superior performances due to the
use of active materials, such as liquid crystals, graphene, and semiconductors. However, the …

Metamaterials open up various exotic means to control electromagnetic waves and among

We propose a dual-controlled switchable broadband terahertz (THz) metamaterial absorber
based on a hybrid of vanadium dioxide (VO_2) and graphene that demonstrates strong …

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 …

Transparent conductors (TCs) have a multitude of applications for solar energy utilization
and for energy savings, especially in buildings. The largest of these applications, in terms of …

With advancements in infrared detection technology, there is a need for fast, switchable
infrared camouflage. Here, we report an adaptive infrared camouflage system that can be …

Metamaterial absorbers (MMAs) offer a novel and flexible method to realize perfect
absorption in specific frequencies, especially in the THz range. Despite the exotic abilities to …
