The LIG based metasurface with a size of 5 × 5 cm 2 can be rapidly prepared in just 5 minutes under ambient atmosphere. The continuous modulation between wave transmission/shielding in an ultra-wide ...

A team of researchers from Hong Kong has developed an innovative antenna. This boasts the unique capability to dynamically, simultaneously, independently, and precisely control all essential aspects ...

Scientists have developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and is expected to play an important role in the integration of ...

(Nanowerk Spotlight) Textile engineering has long been a cornerstone of human innovation, from ancient weaving techniques to modern fabric production. However, the integration of textiles with ...

Working in the terahertz (THz) range offers unique opportunities in various applications, including biomedical imaging, telecommunications, and advanced sensing systems. However, because of the unique ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.

(Nanowerk News) In a world first, the team developed a universal metasurface antenna that allows the independent and simultaneous manipulation of amplitude, phase, frequency, polarisation and ...
