摘要

Spin-multiplexed metasurfaces have emerged as a transformative technology in satellite communications, offering unprecedented potential for expanding information capacity. Despite their promise, conventional implementations employing interleaved and multi-layer stacking architectures are fundamentally limited by inherent efficiency constraints and significant crosstalk interference. This study presents a novel paradigm in spin-selective chiral metasurface design that enables fully independent phase modulation of transmitted and reflected waves while maintaining exceptional isolation between channels. This innovative approach yields a remarkable 97% operation efficiency with an exceptional circular dichroism (CD) of 0.93 across 10–12.2 GHz, corresponding to a 19.8% relative bandwidth, as demonstrated by numerical simulation and experimental validation. The proposed crosstalk-free spin-multiplexed metasurface architecture achieves high-efficiency wavefront manipulation exclusively through geometric phase rotation, eliminating the need for complex multi-layer structures. This advancement represents a significant leap forward in the development of next-generation high-capacity communication systems utilizing circular polarization multiplexing.
