Abstract
Abstract Programmable metasurfaces offer a low‐complexity and cost‐effective platform for electromagnetic wave control, with significant potential in sixth‐generation (6G) wireless communications. Conventional transmissive programmable metasurfaces often rely on reverse‐current designs with complex metallic via structures, which are fundamentally incompatible with transparent dielectric substrates. To overcome these limitations, an optically transparent and integrable transmissive programmable metasurface based on planar huygens resonance is proposed. The design comprises two transparent programmable metasurface films laminated on both sides of a dielectric substrate, enabling direct attachment to transparent surfaces. Through synergistic excitement of electric and magnetic resonances, the metasurface achieves phase manipulation of transmitted electromagnetic waves while preserving optical clarity. Experimental results demonstrate its effectiveness in near‐field holography, far‐field beamforming, and wireless signal enhancement. This advancement establishes a versatile platform for seamlessly integrating electromagnetic functionality into transparent media, opening new opportunities for transparent electronics, reconfigurable wireless systems, and future 6G communication infrastructures.
