Electromagnetic metasurfaces harness subwavelength patterned elements to exert precise control over the phase, amplitude and polarization of incident waves. By engineering anisotropic or chiral ...

Reducing the radar cross-section (RCS) is an integral part of safeguarding assets, augmenting military efficacy, and maintaining a strategic advantage in modern warfare. Research is ongoing to develop ...

Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

A research team has demonstrated the first nonlinear metasurface with engineered nonlocality, that simultaneously delivers high‑Q resonance enhancement and pixel‑level control of the wavefront of ...
