Reconfigurable metamaterials significantly expand the application scenarios and operating frequency range of metamaterials, making them promising candidates for use in smart tunable device. Here, we propose and experimen...

Proposed by von Neuman and Wigner in 1929, bound states in the continuum (BIC) exhibit the merits of ultrahigh Q–factor and strongly confined modes, solving the inherent high dissipation of metamaterials (MMs) and plas...

Spin currents – flows of spin angular momentum without net charge – are central to next-generation spintronic technologies but remain difficult to generate and control efficiently. Magnetic metamaterials provide a po...

While spin angular momentum is limited to ±ℏ, orbital angular momentum (OAM) is, in principle, unbounded, enabling tailored optical transition rules in quantum systems. However, the large optical size of vortex beams ...

In this opinion, we describe the potential of an emerging class of flat optics known as “nonlocal metasurfaces” to manipulate light in both real space and momentum space. While the ultimate form of a conventional “...

Dielectric metasurfaces supporting optical resonances have become a promising platform for quantum and nonlinear optics. However, resonant metasurfaces remain limited in their capacity to independently control the behavi...

Radiative cooling is a passive cooling strategy that leverages thermal radiation to dissipate heat into a cooler environment, offering an energy-efficient and environmentally friendly alternative to conventional cooling ...
