Summary: This paper presents the design and optimization of a dual-band polarization-dependent metasurface capable of dynamically switching transmission and reflection characteristics. By changing the incident wave polarization, the metasurface is able to transform the transmission band into a complete reflection band, and vice versa. Remarkable transmission and reflection characteristics are achieved within the frequency ranges of 6.1-6.55 GHz and 8.9-9.3 GHz.

Summary: A broadband spin-decoupled metasurface is proposed to regulate dual circularly polarized waves independently. An equivalent circuit model is established to relate reflection coefficients and structural parameters, and meta-atoms are designed based on this model to form a 3-bit coding metasurface. Experimental measurements confirm the effectiveness of this methodology for metasurface design.

Summary: All-dielectric metasurfaces provide complete control of light's amplitude and phase at sub-wavelength scales, but their lack of tunability after fabrication is a limitation. This study demonstrates a programmable all-dielectric metasurface made of Sb2S3 PCM, which shows high efficiency phase modulation and reversible optical modulation in the visible spectrum. These novel chalcogenide PCM metasurfaces have the potential to be used in spatial light modulators and impact various applications.

Summary: This study introduces a high-efficiency and broadband spin-unlocked metasurface by combining the resonance phase and the geometric phase mechanisms. The design is achieved by changing one geometric parameter instead of multi-parameter optimization. Experimental results demonstrate the anomalous photonic spin Hall effect and completely independent wavefront manipulations achieved by the spin-unlocked metasurface.
