Scientists at Heriot‑Watt University have demonstrated in a world-first, that light can be used to control every aspect of how electromagnetic waves oscillate, opening new technological frontiers.

(Nanowerk News) Researchers are working to unlock the immense potential of terahertz waves for applications ranging from medical imaging to wireless communications. However, efficiently controlling ...

Fig. 1. The dielectric response models for conventional dielectric materials and for metamaterials. For conventional dielectric materials, there are three types of polarization models: Drude model for ...

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
