A compact dual‐functional reflective terahertz (THz) metasurface is experimentally demonstrated. Near‐unity linear‐to‐cross polarization conversion is achieved at four resonance frequencies: 0.65, 0.80, 2.02, and 2.48 THz. Broadband linear‐to‐circular polarization conversion is realized in two bands, 0.86–1.95 THz (77% fractional bandwith, FBW) and 2 ...

Biodegradable Adhesive Systems for Bio‐Integrated Applications
Biodegradable adhesives provide temporary yet reliable adhesion while degrading into safe, non‐toxic by‐products under physiological or environmental conditions. This review summarizes recent developments in physical and chemical adhesion mechanisms—including hydrogen bonding, catechol chemistry, amine‐carboxyl coupling, and emerging diazirine and urea

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.
