Broadband, Single‐Layered, and Optically Transparent Reflective Phase‐Shifting‐Surface Array for Beam Manipulation and Enhanced Wireless Communications

Advanced Electronic Materials, EarlyView.
A novel optically transparent reflectarray design approach based on multi‐resonant phase‐shifting elements with minimal fine metal line (FML) structures and low‐loss single‐layer cyclic olefin copolymer (COC) substrate is proposed. The design achieves exceptional antenna performance while ensuring high optical transparency, validated through wireless ...

Realization of Non‐Equilibrium Wurtzite Structure in Heterovalent Ternary MgSiN2 Film Grown by Reactive Sputtering

Advanced Electronic Materials, EarlyView.
The piezoelectric and ferroelectric applications of heterovalent ternary materials are not well explored. In this study, c‐axis‐oriented epitaxial MgSiN2 films with the wurtzite structure are successfully grown on (111) Pt//(001)Al2O3 substrates by reactive RF magnetron sputtering at 600 °C under pure N2 atmosphere.
