Robots and autonomous cars will have eyes that see much more than the human eye is capable of, a review of the growing field of meta-optics has found.
Peripheral photoinhibition (PPI) direct laser writing (DLW) is a lithography technique used to fabricate intricate 3D nanostructures that are widely employed in photonics and electronics. PPI-DLW uses two beams, one to excite ...
A research team co-led by a scientist at City University of Hong Kong (CityU) has developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and is expected to play ...
A research team, led by the Nano Optics Group within the Department of Â鶹ÒùÔºics at UNIST has reported achieving all-vanadium dioxide (VO2) multifunctional metasurfaces, which perform as a transparent window in the broadband ...
Metalenses, compact lenses made with metasurfaces, have the potential to enable thinner, lighter, cheaper, and better imaging systems for a wide range of applications where miniaturization is critical (e.g., for mobile devices, ...
In metasurfaces, surface lattice resonances (SLRs) and bound state in the continuum (BIC) are two convenient approaches for achieving high quality factors (Q-factors).
There is a long-standing folk art in China called "rice carving," in which lifelike artistic patterns are carved on rice with a length of only about 5 mm. These works need to be appreciated with a magnifying glass.
A new publication from Opto-Electronic Advances discusses highly efficient vectorial field manipulation using a transmitted tri-layer metasurface.
While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.
Metamaterials and metaoptics offer a broad dimension to explore exotic functionalities in physics and optics. In a new report now published in Science Advances, Jie Peng and a team of scientists in physics and interdisciplinary ...
