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 …

The increasing demand of unoccupied and unregulated bandwidth for wireless
communication systems will inevitably lead to the extension of operation frequencies toward …

The field of terahertz science and technology has been an active and thriving research area
for several decades. However, the field has recently experienced an inflection point, as …

According to Edholm's law, the demand for point-to-point bandwidth in wireless short-range
communications has doubled every 18 months over the last 25 years. It can be predicted …

The development of artificially structured electromagnetic materials, termed metamaterials,
has led to the realization of phenomena that cannot be obtained with natural materials. This …

Over the past two decades, terahertz time-domain spectroscopy and quantum-cascade
lasers have been two of the most important developments in terahertz science and …

We experimentally demonstrate, for the first time, an optically implemented blueshift tunable
metamaterial in the terahertz (THz) regime. The design implies two potential resonance …

Gate-controllable transmission of terahertz (THz) radiation makes graphene a promising
material for making high-speed THz wave modulators. However, to date, graphene-based …

We design and implement a multipixel spatial modulator for terahertz beams using active
terahertz metamaterials. Our first-generation device consists of a 4× 4 pixel array, where …

The development of components for terahertz wireless communications networks has
become an active and growing research field. However, in most cases these components …
