Hybridization of surface lattice resonances induces dual-band bound states in continuum

In metasurfaces, surface lattice resonances (SLRs) and bound state in the continuum (BIC) are two convenient approaches for achieving high quality factors (Q-factors).

Metasurface-based nanoprinting: Displaying optical images at the nanoscale resolution

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.
