Summary: Traditional OVDs face risks in the face of increasing counterfeit threats; Metasurfaces, as candidates for the new generation of OVDs, exhibit multiple optical responses and provide a more robust solution for optical anti-counterfeiting; mOVDs have multiple optical responses, are difficult to reverse engineer, and are key points of discussion in terms of fabrication methods and classification.

Summary: Wireless power transfer (WPT) systems enable long-term operation and miniaturization of implantable devices by eliminating the need for battery replacement and wired power supplies. However, the practical application of wireless power transfer systems for implantable devices is challenging due to constraints and requirements of the human body, such as tissue reflection loss, small device size, and electromagnetic wave attenuation.

Summary: Active metasurfaces with tunability have attracted significant attention from industry, but practical solutions are currently limited. This paper proposes an electrically tunable active metasurface using photoaligned nematic LC and demonstrates its applicability. The high quality of LC photoalignment on the metasurface is demonstrated, and tunable transmission for telecommunication C band is achieved with a modulation depth of 94% at 1530 nm. The sub-millisecond response time is achieved at a temperature of 60 degrees C, showing the potential for fast-switching photonic devices at optical communication wavelengths.

Summary: This paper introduces a new method to solve two important problems in the propagation phase of a dielectric metasurface by designing a metalens. This method not only increases the metalens transmittance and improves the light uniformity, but also effectively reduces the metalens spherical aberration, providing a new approach for designing high-quality metasurfaces.

Summary: The article introduces a simple and efficient method for designing wave-shaping materials with specific wave scattering effects, including multiple scattering effects and magnetic and electric polarizabilities, as well as applications in designing aperiodic metasurfaces. By extracting the eigen-polarizabilities of the system, it is found that a large eigen-polarizability corresponds to a large collective response of the scatterers.

Summary: By exploiting the topological features of non-Hermitian matrices near singular points, an additional degree of freedom was introduced to address optical phase engineering in optical metasurfaces. Choosing metasurface building blocks to encircle a singularity allowed for the engineered full 2π-phase on a specific reflected polarization channel with topological protection. The ease of implementation and compatibility with other phase-addressing mechanisms demonstrate the industrial applicability of topological properties in metasurface technology at optical frequencies.

Summary: This study proposes the concept of angular momentum holography, which can fully synergize spin angular momentum and orbital angular momentum. It demonstrates the reconstruction of spin-orbital locked and spin-superimposed holographic images using a single-layer, non-interleaved metasurface. The designed dual-functional AM meta-hologram enables a novel optical nested encryption scheme, offering parallel information transmission with ultra-high capacity and security. This research has promising applications in optical communication, information security, and quantum science.

Summary: Photonic time crystals are artificial materials with spatially uniform but temporally varying electromagnetic properties. This study extends the concept of photonic time crystals to two-dimensional artificial structures called metasurfaces. By designing a microwave metasurface, the researchers confirmed the existence of momentum bandgaps and exponential wave amplification, demonstrating the potential of metasurfaces as a material platform for emerging photonic space-time crystals and for amplifying surface-wave signals in wireless communications.
