Human visual neurons rely on event-driven, energy-efficient spikes for communication, while silicon image sensors do not. The energy-budget mismatch between biological systems and machine vision ...

Electromagnetic metamaterials are artificial structures with electromagnetic (EM) properties not found in nature. Into the new century, the two-dimensional (2-D) counterpart of metamaterials, which is ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250229. Programmable metasurface (PM), also termed as reconfigurable intelligent surface (RIS), have emerged as a ...

But as with other antennas, once the AM leaky-wave antenna is fabricated, its radiation characteristics are fixed. At about that time, Dr. Dai Junyan, from a research group led by Academician Cui ...

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 ...
